I don't do a lot, but here's what I've received since the beginning of the year (some of these were earned last year, but I received the checks or cashed in this year).
eBates: $32.16 (should have another $9 for this quarter)
Ford Test Drives: $150 (one for me; one for DH)
Greenfield Surveys: $36 (rcv'd $15; waiting for $21)
MySurvey: $20 (think I'm close to another $10)
Pontiac Test Drive: $50
Viewpoint Forum: $20.53
MyPoints: $100 in webcertificates
Mazda Test Drive: $35 in GC (altough I'm still waiting for this--time for a call?)
GoZing: $4 in
Amazon GC
Vividence: $5 in Amazon GC
AT&T Survey: $10 in Amazon GC
Amazon: $30 in Amazon GC for buying from their Apparel store, plus the $5+ in Trivia nickels
Disney Visa: $17 in Disney Dream Reward Dollars earned
I think that's a grand total of $509.69 for the year. I spent about $28.86 on Tupperware and the Amtrak ticket and the plastic webbie card. But that still leaves my total at around $480. Yes, I have a spreadsheet that I started at the beginning of the year. Last year I received $50 in Barnes&Noble GC and $25 in Rainforest GC from MyPoints. Plus $30 from MySurvey. I think that's all I was doing last year. Oh, plus around $20 from eBates, I think. I wasn't keeping track then. And I also do LuckyPoints, PCHPoints, Memolink, Creation Rewards, and Blink, but I haven't tried cashing in at those yet.
HTH!
