Buyer pays YOU for shipping, and then you actually buy the shipping label.
Fees are taken out of the entire transaction, including shipping and any state taxes.
I'm guessing it was the plate for 22.50 + ~$7.50 shipping. Assuming 7% sales tax, the total transaction in this example would have been $32.10.
$32.10
-7.50 label
-4.33 eBay fees
-2.10 sales tax.
-0.40 per transaction fee.
= 18.09
Of course variations in shipping location and tax percentage per buyers actual location can change that, but it sounds like your ~$19 is correct. Did you do Promoted? Whatever percentage you set for that also would come out of the 32.10.
