Why I built Pennysleeve

I play Magic, and building a deck out of local shops was harder than it needed to be. I could not tell which shop had the cards on my list. I phoned around, I drove out, and I still came home short. Every trip was a guess, and the shop that had what I wanted often never knew I was looking. That is the problem I want to fix.

Fixing it needs shops to list what they hold, so the tracking came first: a shop that is not already tracking has nothing to list. The search over those lists is open now, and it is only as good as the shops near you that have turned their list on. Find cards needs Seller, and Storefront needs Business.

I buy and sell cards too, so I wrote software to run that side of it: what I paid, what came out of the box, what sold, and what is still sitting on the shelf. Pennysleeve is that software, opened up to other people. It is what I run my own card business on.

One person builds Pennysleeve, and that person is me. Brad. I write it, I answer the mail, and I fix what breaks. I put that on the page because it should change what you expect: straight answers, sometimes slow ones, and nothing sitting between you and the person who can actually change the code.
