I diligently enter all my purchases (at least those that have receipts) into GnuCash. I’ve been keeping track of my purchases since 1994, which means that I can, at a glance, see that I have paid, for example, at least $6,367.08 in GST since then. (Ouch.)
In doing this, I’ve begun to notice how certain stores’ receipts are a complete waste of paper. For instance, I’m looking at a receipt for a birthday card I bought for Dave Raso, and it is ten inches long. That’s right, for one $3.29 birthday card, I got ten inches of cash register receipt.
I’m sure I’ve seen other more egregious examples – if I find them, I’ll post pictures here. What’s the longest cash register receipt you’ve seen for a single-item purchase?
I'd have to say anything I get from bestbuy/future shop.
