Coupon Cabin has great customer service and bonus cash back as well. One improvement is that it would be nice if coupon cabin would notify customers via their email address when a sale posts. I like that ebates.com notifies customers via their email address when sales post. I like the fact that I get more frequent small checks from coupon cabin versus every 4 months from ebates. These are the only 2 rebate sites I use as they both have great customer service although lately I have only used couponcabin.com.
