Fees of sending USDT is pretty cheap on any blockchain besides Ethereum which will cost you like $5-10 a transaction on a good day. Unfortunately a lot of exchanges doesn't support USDT withdrawal on other networks besides Ethereum.
$5 to $10 is also quite a large fee, especially if the USDT is a little of course they will consider sending it again because it costs more than 1$.
Do you think there is a delivery where the fee deduction is only $1 or $2.
