Lower costs for buyers. Reduced fees for sellers.
As both a seller and buyer on TCGplayer, I grew tired of the old interfaces, endless surveys, recurring bugs, and rising fees without meaningful improvements. I moved my buying and selling to Mana Pool. I now see better pricing on high-end cards and stronger deposit payouts because the fee structure is lighter.
- Buyer win: More savings on high-end singles.
- Seller win: Reduced fees keep more money in each deposit.

⚠️ Expect bigger swings: Collector Booster EV is top‑heavy—a small number of chase cards/treatments carry much of a box’s value. Because the tool samples outcomes, runs can vary meaningfully. Run the calculation multiple times to see how wildly the average swings. For a steadier picture, consider the entire range between the low to high and review the confidence bands.
