OP： paying via Check & Amazon GC

OP is a generous survey site which pays 1-10 dollar per survey and up to 100 dollar per focus group. I got paid many times (totally over 300 dollars in this year 2009).
It pays via check (5 dollars minimum) and Amazon GC (1 dollar minimum). Cashout via Amazon GC is instantaneous which cashout via check takes about 1-2 week.
