I do this too, but for different reasons. It just seems like interesting personal data I could analyze some day. Does anyone know a practical way to grab this data electronically for analysis? I have shoeboxes full of receipts... I could tell where, when, and what I bought for the past 10 years. Merge that with photographs and emails and I've got a heck of a personal journal... problem is, i can't figure out how to enter the data short of hiring someone.

Could you use Amazon's Mechanical Turk?

Good idea. i'd just have to have the neighbor kid scan everything in, first.

Dude, relax. Your paper receipts are not needed, your bank has a digital record.

It always good to keep a copy, you never know when you'll get overcharged for tip or something of the like.
