I've been looking over the various survey and webclick sites I'm a member off, and have decided to start keeping a record of how much I've made off them. I also thought I'd put up some referral links, in case anyone is interested in joining.
EmailCash - get points for shopping through their affiliate sites, for doing surveys and for reading occasional advertising emails. Convert the points to dollars and when you have enough, order a $30 cheque. So far I've made $90 from this site. Without shopping with their partners, it takes me about 7 months to make $30. Australia/NZ only.
SpiderMetrix - get points for surveys, and use the points to buy vouchers or cash. So far I've got one $30 amazon.com voucher. This site is a lot slower than EmailCash, and it seems most of the surveys they send me these days only work in IE, which I don't use. Open to various countries.
YourVoice - run by AC Nielson. Get points for surveys. Better amounts of points than EmailCash. Points can be used to buy items from the rewards catalog (including gift vouchers) or donated to charity. Please give me your email address for a referral. Last redemption I got was $80 of Coles vouchers, but I've had stuff from them before. Australia only.
That's What I Think AU - Get points for doing a survey about movies once every few months. Slow to get points. They do now offer Paypal payments, though it takes about 45 days for them to process. I've had $15 so far. Australia only. If you want a referral, please give me your email address.
Pure Profile - get cash rewards for doing surveys and clicking on sponsored links. When your account balance gets to $25, you can have it direct-deposited into your bank. So far, I've earned $111. Australia only.
Lightspeed Panel - do surveys, and get paid into Paypal. I've been paid $10 by them so far. Australia only.
Ciao Surveys - I just joined this one today. Looks like it pays cash amounts for doing surveys. Pays into Paypal. Australia only. Please give me your email address for a referral. Very slow.
OzRewards - cash rewards for online shopping with their partners and for joining affiliated sites. Pays cheque, Paypal or vouchers. Australia only. Starting bonus of $1 credit. I've so far (in about 3 months) got $10 of rewards there without shopping through them, though I think the minimum redemption value is $25.
FreeStuffDay - not a rewards site as such, but a fun competition site which has a stack of prizes from various business, and during the once-a-month open time, you log in and try to win something. It can involve hours of refreshing of pages, but the prizes range from keyrings and pens to toys, toiletries, vouchers, all the way up to cameras and holidays! I've won a nice necklace pendant from them. Australia only.
