CamelCamelCamel. Amazon only, though – and who knows if they'll be shut down too under this policy.

I think PriceZombie ran afoul because they compared Amazon's history to other competitor's websites like Walmart, Best Buy, etc.

CamelCamelCamel just compares the current Amazon price to historical Amazon prices.

One site makes it much easier to encourage you to buy on another site, one site makes it much easier to optimize your purchase while still remaining with Amazon.

> This situation is further compounded by our competitors (who only index Amazon) being allowed to continue despite utilizing Amazon's data in the same manner as we did without facing similar bans.

Looks like being Amazon only may be what is keeping them alive. I enjoy CamelCamelCamel a lot, it's fun to put in a low-ball price target and then months later get an email that it has been met.

SlickDeals developed something similar but my understanding is that Amazon "asked" them to kill it or severely cripple it. Amazon's got a big stick and isn't afraid to weild it.l here.
