Hi, I'm Callum - the developer behind the Fee Reveal and eBay VAT Extractor Chrome extensions.

By day, I run Kallzeh, an online tech resale store specializing in refurbished laptops, tablets, and MacBooks. As a fellow eBay seller, I know first-hand how frustrating it can be to track down hidden transaction fees, dig for postage costs, or manually calculate VAT for your accounting.

I built these extensions to solve my own headaches and speed up my operational workflow. I've decided to share them to help other sellers save time, ditch the manual spreadsheets, and reclaim their margins.

While these tools are free to use, keeping them running smoothly means constantly rewriting and updating the code whenever eBay decides to change its page layouts. If my extensions have saved your business a few hours of misery or helped you spot hidden costs, consider buying me a coffee!

Your support directly fuels the late-night coding sessions required to maintain, fix, and improve these tools for the seller community. Thank you!
