They do pay through paypal now but you need to select it as your preferred payment method by contacting them. If you don't they will send you a check after you complete the survey.
I signed up a few weeks ago and hadn't got anything, but then about 4 days agao they sent me my first survey and I have received two since. Plus I already have a test product (got it in the mail today) and it is a $10 payout once I submit my opinion!!
