I was also asked to blog about which survey sites i recommended to use as coupons. Well, it’s hard to say so far I’ve only been doing them for a month and you have to reach a minimum with all of them before you cash out.
Lightspeed – I reached the minimum in a week, but I haven’t gotten any surveys in a while
Survey Spot – is the best for product samples and online panels (which pay big)
All the others the jury is still out on. I’ll update the list as I know more.
