Something that when I get an email receipt in gmail I can forward to my unique address (or filter in gmail).
I get Canada Post emails that are such a pain in the ass to do accounting for, but even something like monthly saas emails would be great to forward and it detect amount, taxes paid, category, etc. (and let me email to that address in the way this site does as well)
Here's at least two people who want it, who's going to build it? ;-)
I would love to beta-test, if anyone's listening.
With respect to beta testing, according to http://blog.onereceipt.com/post/9256372304/hello-world, posted one week ago, they're going to start sending out invites to people who registered their interest 'within the next few weeks.'
If you want an early invite, they'll give you a referral email after you register.

Right now Mint does a decent job categorizing most of my other purchases based on vendor, but every month I end up with a huge, opaque line item for Amazon. Really hampers my budgeting.
(I have the same problem with Target and Wal-Mart, but to a lesser degree--they don't carry as wide a variety of stuff as Amazon, and I shop there less.)
