I saw a watch on eBay with a retail value of $89.95 and bought it for about $28. It was one of my favorites from Casio, the Databank series. I was looking to replace my old Databank watch which the pin holders wore out on after 6 years of use.

The old one isn't even made anymore. It was a great watch, especially good for when you're in a store and need to calculate tax to make sure you have enough if you're not sure. Also, storing phone numbers in it was cool too. The new one has all the capabilities as this old one, plus a lot more.
