You send multiple trades and store the potions in the trades themselves. This basically means you'll have to either trust that the buyer will send all of the potions in consecutive trades, or you'll have to swap collateral until you get the potions you're owed. Messy I know.

Because of this, almost no one sells power 17 and 18 cards for potions anymore. People mostly do card trades, exchanging multiple cards for other cards of equal worth.
