These are used at our business. I like having the three copies for the receipt. My only complaint about them would be that it is difficult to tear the receipts from the binder of the book. The receipts get wrinkled or torn when removing them from the binder.
I purchased this receipt book along with two-three other types since I wasn't sure which would be the better choice. This one is by far the best choice. The paper used is a much higher quality than the other brands and the receipt copies are clear and smug-free compared to the others. I also like the "Note" space that is provided because it allows me to use a pre-inked business stamp for company identification. If you need a receipt book for cash transactions (or for any other than credit cards) this truly is the best option I've encountered so far.
