i assume letsbuy would put you on a queue considering there are going to be a limited units available. and once they have a unit for you, they would ask you for the payment options. letsbuy worked fine for me. i ordered an optimus one from it and it was delivered with some delay. the only thing i hated was that the courier company they used did not deliver it to my place saying that my house was out of their service area. so i had to go to their warehouse to collect it myself pretty much nullifying the advantage of ordering it online.
