I used to use alsotao.com but I see they are down now. They were pretty good though and cheap while they lasted.
Which one now would be the cheapest but reliable and accept paypal? Bhiner shipping is too expensive.
I use Bhiner all the time, they MIGHT be a little more expensive, but especially over the last 6 months they have really good speed and service, they use express domestic freight to get the stuff to them in almost all cases, and have been packaging up items for international shipping really quickly lately.
Example, my most recent order last week, I paid the international shipping on Monday night, it arrived in the country Thursday, and it was on my doorstep in New Zealand by courier on Friday afternoon, 4 days door to door China to NZ, at any time of year that would be fast, at THIS time of year it was astounding. Sent using their new "Bhiner Express" shipping the weight including packaging was 2.664kg, the international shipping was 44.10 USD, and for me it came via EMS. Pretty good deal if you ask me.
Combine that a shopping cart that actually works mostly properly, photos taken when items get to the warehouse, and they can read and write somewhat sensible english... any small increase in cost is well worth it in my opinion.
Of course, if you want stuff sent by the slow-boat-from-china, they don't offer that, but typically in those cases Aliexpress is the better choice anyway.
