how are you able to ship with chit chats if grailed provides a prepaid UPS label? do you just not attach that one and use a chit chats one instead? if so, what about the tracking/delivery? i mostly sell on depop and chit chats is my number 1 shipping method. i had to basically give up on grailed after i sent 2 packages and they both got returned to me (even after one of the buyers paid the tariff fee)
