Here's what I'd like: for some ambitious web engineer to figure out a way to aggregate a list of all stores that offer affiliate discounts, and then what affiliate to use.

For example, I often try eBates and Fatcash to find discounts on online purchases. I also try coupon sites like retailmenot to see what I can get. But with airline partner sites, there's a whole other world of potential affiliate bonuses out there, and each one is different. That's a lot more sites.

I recently spent a lot of money at ImprovementDirect, only to find afterward that I could have gotten up to 5 miles per dollar on United. Painful.

Is there any site out there that does this? Anyone interested?

Of course, I'm not sure how such a website would make any money . . .

Try this:
http://rewardsdb.com/

Wow. That's an excellent site. I've been missing out!

Thanks!

I use http://www.evreward.com, RewardsDB is actually much nicer than when I last saw it, but I think I still like EVReward a bit better (little cleaner and easier to read I think).

evreward is a lot easier, though not always as quickly updated. Rewardsdb is a bit more cluttered and less "clean."

I usually check evreward first, and if I don't like what I'm seeing, will then go to rewardsdb.

Thanks! I hadn't known about these (and missed some cash back on purchases, too, drat!).

P.S. I wonder if a moderator could change the title to something more descriptive?

Yes - both suggestions are great. And, I agree, a re-title would help get the word out.
