Thrift's Wandering Post

You jingle a significant pouch of coinage to summon forth a being of commerce from another plane. The spell slot level you use to cast this spell determines the gold and value of the merchandise the being has on-hand, as shown in the Spell Level Storefront table below. The being is able to sell any items of a value equal to or less than the value shown in the Merchandise Value column. The being is neutral towards you and your allies and simply returns to its plane of origin if any hostile interaction takes place. The being does not materialize the gold on-hand until the transaction has been completed and the DM determines the being’s creature type. You are able to do business with the being and it returns to its plane of existence when you end the spell.
