Maxim tracks your email/physical address(and maybe even first and last name?) now-a-days.
Really? In December I ordered some Samples from Maxim and they shipped to my home address, via FedEx 3-Day, straight from the factory in Asia. I also used my personal email (well, I guess it's also a business email; the domain points to my website/blog, which says I'm a consultant, so maybe they actually looked).
Never had a problem with TI either, even recently. Samples are easy to order, just go to the product page, click samples, add the appropriate part to the cart and checkout. TI has always shipped my samples via UPS (sometimes FedEx) Next Day Air.
I wish TI had a "No Rush" option for samples. I wouldn't mind Ground shipping a lot of times. Hell, half the time I feel guilty ordering samples from them because I imagine what shipping must cost. In the last year or two, I've noticed about half of the samples are coming direct from the factories in the Far East, which I guess makes 1-2-3-Day Air the only feasible option. In the past, all the samples came from Texas.
Something I've started seeing recently (particularly with things ordered through the TI Store) is that the FedEx tracking number issued is like a virtual or meta number. By that, I mean you see the package leave Taiwan, it ends up in Forth Worth or Dallas, TX then makes its way to you. But in actuality, it's two or more discrete shipments. I suspect they're shipping an entire cargo pallet full of orders from Taiwan to Texas, the pallet has a waybill number, which my (and all the orders in that container) reference or link to. It gets to Texas, where it's split up and the individual boxes are scanned into the system with their own waybill number, which again links to my tracking number. This is then picked up by FedEx makes its way through the Atlanta hub and is delivered to me.
I know FedEx has this capability and, based on the way the tracking info shows up and the labels on the box, I'm pretty sure is what TI is doing. Which is pretty slick. Must save them hundreds of thousands in shipping costs every year.
