I have been doing these surveys for the 'military shopper community' for seems like forever. I didn't even realize they gave rewards until just now! I don't think I saw anywhere in their emails, anything about your rewards. I must have joined this when DH first joined the service (2 yrs ago). I clicked the link to their FB page, then saw a post about 'thank you for my amazon GC' posted on their wall. Then it dawned on me. I found a link to the site itself (the emails only have a link to the survey--then it closes and no link back to the site) and checked, I had 675 points! 500 equals a $5 Amazon GC! WOO-HOO!
I am such a nerd I can't even believe that it never dawned on me. I have applied to other survey programs before and been denied, so I guess I just forgot about it. lol
