WalletSaver is a Chrome add-on developed by themonkeyslat that aims to help users save money by preventing them from buying unnecessary items online. With this add-on, Terry Crews (or any picture of your choice) becomes your digital guardian, protecting your wallet from impulsive purchases.

WalletSaver currently supports eBay, allowing users to browse the website without being tempted by unnecessary purchases. The add-on works by analyzing the product listings and identifying items that may not be essential or within the user's budget. When such items are detected, Terry Crews appears on the screen, reminding users to think twice before making the purchase.

The add-on is open source and can be found on GitHub at github.com/MonkeySlut. Although it currently only works for eBay, the developer has mentioned that support for other popular online marketplaces like Amazon and ASOS is in the works.

With WalletSaver, users can have a fun and helpful tool to keep their spending habits in check, thanks to the ever-watchful Terry Crews.
