Survey Hacks (Tips & Tricks)
1. If the survey reward is a coupon discount, there's probably no limit to how many times you can take the survey and get your free coupon, do it every day if you'd like (you just need a valid survey invitation).
2. If the reward on this survey is a sweepstakes entry, check official rules for max number of entries per entry period. There is often a limit, but usually you can enter multiple times to increase your chances of winning.
3. No survey invitation? Just go there and buy something super cheap, save the receipt - poof, you should now have a valid survey invitation.
