I received an email to tell me I had reached the cash out threshold. It was then straight forward to choose how I wished to be rewarded and to order my vouchers which arrived within a couple of days. Painless procedure.
Interesting surveys, although sometimes it can be a little frustrating when you are rejected by a few in a row. The rewards are sometimes quite small but they add up reasonably quickly. There are opportunities to earn extra with the spin feature and you are paid for looking at emails.
