CardLuma Insider
Dealer-to-dealer guides and field notes for people who actually run a card business — eBay store strategy, pricing, listing mechanics, shipping. Written for operators, not beginners.
What CardLuma Insider Is
Practical write-ups on the things that actually move the needle. How eBay search really works. When an eBay Store starts paying for itself. Plain-white-envelope shipping and when to use it. Item specifics that buyers filter on. Pricing that sells without leaving money on the table.
Some pieces are public — anyone can read them. Others are members-only, written for sellers running the platform day to day. Either way it’s dealer-to-dealer: the stuff you’d trade at a show, not a press release.
No blog-mill filler. No “in today’s digital landscape.” Just how the work gets done, from people who do it.
