Shopping Reward Programs, Bad ones

Before digging into my favorite reward programs, it would be better to talk about some NOT so good ones.

1. MyPoints, ranked worst for two years in a row. People estimated that if you buy from them, 63% (78 out of 124 total merchants)of the time, you get paid with least refund. They only offer high refund for only a few merchants like Noble, Overstock and SmartBargains.
2. Greenpoints, offer rewards only toward to 101 merchant. They have lowest for about 25% of the time. They pay in point, but you can convert to gift card later.
3. Freeride has only 79 merchant on their chart. The have lowest of about 23% of the time you buy from their site, roughly about 12 merchants in their chart.
4. Memolink has lowest of 32 times out of 163 (their total merchants in their chart).

I would recommend to keep away from these sites. If you would like a try, it is ok. But remember if you find these sites are not as good as you expect, turn to the better sites.
