Purchased vintage sew in pockets today 1st of July 2022. Pockets. 7.50 Postage 4.00 Tax. 1.38 GST 7% and PST 5% = 12% Probably obvious fyi as the buyer you pay the tax of your Province; and you pay the tax for the postage as well.
Technically speaking, the tax is being charged on the shipping charge, not "postage" which is a slightly different animal (particularly in instances when the item isn't going by mail).
Marnotom! In this case the item is being sent "letter post" hence the term "postage". Shipping is a nebulous term as it includes postage but also handling packaging materials etc., but to be correct eBay used "shipping" on the invoice.🙉🙊🙈
