Came across a site called BonusPit.com (can't post links sorry - yeah, lurker

You enter your card application dates (along with other pertinent dates etc) and it checkes it against eligibility rules. You can then look at a list of offers you should be eligible for. Neat idea, although the matching against rules is opaque and I'm not sure how well it's implemented - are the offers up to date, does it take into account specific card rules like the Sapphire rule etc..

Does anyone have experience with it or know of other similar sites?
