On DroppingNow, both buyers and sellers save on gas fees by dropping multiple NFTs at once as a "bundle" using our bulk drop functionality. Dropping multiple items at once helps distribute gas costs across multiple items (as opposed to doing each individually) and savings on gas can be 10% or more.
If a user dropped a 20-count MLBC bundle, buying this might cost .0576 ETH in gas fees. Buying each NFT individually would cost .0104 gas. So the per/unit gas cost for the bundle is .0576 / 20 = .00288... so 3.6x cheaper to buy the bundle than each NFT individually.
