Are we just paying shipping? That's very generous.

No - it's even cheaper. You don't need to pay anything and get it delivered for free.

But let's take it serious:
https://www.eevblog.com/forum/metrology/ultra-low-noise-reference-2dw232-2dw233-2dw23x/?all
In that (org) thread there was made a rough calculation, based on the buy price zlymex could achieve.
Main target, wasn't to get it the cheapest way
- 1st target was to get it anyhow
- 2nd to buy from a trustable source and the right product

[TiN]

VintageNut and all,

I'll create separate thread on PCB Module design for this project. So I invite everyone to think clearly what they need most on PCB, so you would be ready once the thread emerge. Don't post on this here, to keep offtopic out.
I'd assume qty about 100 boards. That will get each 2pcs if we get 40 people. CAD files will be open.

I'm off. With all these latecomers it is to much hassle and to costly to ship 10 pcs from US to EU.
 Thank you anyway.

Here is the deal for shipping/postage.

USPS International First Class letter/envelope fee is between USD $2 and USD $3 for up to 3.5 ounces  (100g) for Europe, Australia and Indonesia. There is a stipulation for thickness of envelope not to exceed 1/4" (6mm). When the parts arrive, I will make up some envelopes and take them to my post office to see if the envelopes are acceptable for international first class mailing.

I will have to acquire enough envelopes and see about possibly adding some protective padding.

Preliminary prediction is that I will round up to USD $3.00 which should cover the postage and materials.

The issue to discuss is that there is no tracking for this low cost service. Any service that includes tracking will cost more than the parts are worth for 10-12 pcs, a lot more. Stupid money kind of more.

Feel free to chime in with your thoughts and suggestions. 

[Cerebus]

There is a stipulation for thickness of envelope not to exceed 1/4" (6mm).

I have a suspicion that this is going to be the hard constraint. Those cans look kind of TO-5/TO-72 sized and with any (necessary) padding are going to push a package over 1/4" thick. We might end up having to look at some slower small packet rate to keep the postage proportionate. I'm guessing as I know USPS is as arcane as the Royal Mail when it comes to finding the 'sweet spot' in sending something without paying an arm and a leg.

I'm OK to pay for a tracked packet airmail, as it would be silly to lose the lot after all this effort . I am also quite sure from my experience that it would be not possible to use a letter post, as 6mm max thickness is definitely not enough to accommodate the parts in a proper packaging. Please look for the next size up (small packet post?).

Cheers

I've shipped a lot of small parcels in the US.  6X9 bubble mailing packs are about 28 cents at sams wholesale.  Haven't bought any lately and they may not carry them now.  Other places they cost 50 to 70 cents each.  I used to cut them in half and that would be sufficient for 20.  First class parcel is around $2.70 and that is the same for up to 3 ounces.  Oddball packager size doesn't matter.  3 oz is a lot of parts.  On ebay online shipping this is about 2.30 now and they include tracking for free.  If you register with USPS for online shipping the postage is cheaper than retail and they may provide tracking free to boot.  If you have a printer, the printing of labels saves a lot of work and they will fit on the half package.  Just providing evidence that a package has been shipped to an area code should be sufficient for most people.  Don't forget you will need wide clear packing tape.

EDIT;  I just had to re register at USPS to check US pricing.  3 oz is $2.62 and they no longer offer Click n Ship for this size package.  Might as well just go to the post office. I can't believe it as I used to use it.  I get lots of things with lousy packing and they still seem to arrive just fine.

If you read the other thread carefully, you will see that Zlymex stated that he has difficulty receiving electronic payment where he lives. He want this community of interested hobbyists to make some measurements of noise of these parts and share the measurements.

So, our part in this effort will be to repay Zlymex's kindness with public sharing of what we will do with these parts and to share our measurements.

I am doing some research to see how I will be able to measure the noise of these parts where they are mounted in a circuit and running.

[Cerebus]

I've shipped a lot of small parcels in the US. 

Yes, but we're talking about shipping from the US to a lot of destinations that are not in the US.

[Alex Nikitin]

By the way, it would be much cheaper to send the lot for all UK participants to a single address in the UK by a tracked airmail packet and then forward it over here using Royal mail. I can do it if required.

I was just about to suggest the same. How about all of you EU people here discuss where the best place in the EU is for organizing this. From a sheer numbers standpoint, most of the participants are in Germany. It may make sense to send the entire EU lot to Germany.

There is a stipulation for thickness of envelope not to exceed 1/4" (6mm). When the parts arrive, I will make up some envelopes and take them to my post office to see if the envelopes are acceptable for international first class mailing.

At my local post office, they have become quite strict about this.  They have a board with a 1/4" slot in it, and the envelope has to pass through.
If you give the envelope to your mail carrier, they are not going to have one of those, so you could probably fudge it.  I don't know if it would be kicked out later and returned.

The issue to discuss is that there is no tracking for this low cost service. Any service that includes tracking will cost more than the parts are worth for 10-12 pcs, a lot more. Stupid money kind of more.

I think the next step up is $13.50      So, either they have to go overseas in bulk, or people outside the US should just order them from China

I will probably forward at least one box to EU. Maybe one to UK and one to Germany.

[2N3055]

Here in Croatia, you can send letters as a scroll, basically in tube format..  50-100g cca 2€ to EU zone..
They consider it normal letter, just care about weight.. Actually they require tube not to be too small...

I was like  scroll  ..    I asked do they ship stone tablets too...
Guy laughed, and said that many legal documents are sent that way to protect them..

So is there such a service USA->EU  ? That would be a solution.

I can't speak for the others, but for me personally, this is more about getting hold of identified parts from a batch that Zlymex has already sample tested with good results. I'm grateful to Zlymex for taking on the expense of purchasing and shipping them to the US. If I have to pay $13.50 or more for the privilige of receiving them then I will be well satisfied. I really don't care that they're $0.25 in China, or whatever - this way I can be sure of what I'm getting!

It looks like 5 members is the UK. I can send one box to the UK and the UK group can divide them up.

[VK5RC]

Australia looks not well supported (i.e. bulk send not worthwhile), but if post is only $10-15, I would happy to pay that if it  reduced hassles.

Likewise for me.

[VintageNut]

There is a USPS First Class Pacakage rate. I can package up the parts in a small box and send the parts to one member in each country that wants to do this. You could share the shipping cost among the group in each country. Below are  are the rates. I don't know about tracking but i will find out.

UK  USD $13.50
Germany  USD $13.50
Australia  USD $13.75

If you want, you can purchase the shipping label online, print the label to pdf, and then email the label to me. I will provide the small boxes.

Its an option.

I can not say better, I will pay for the safe shipment and less hassle to Vintage nut.
