Whenever I saw the e-mail that I had sold something, the first thing I would look at was whether the buyer was in Canada or the U.S.
The last couple of days, the e-mails I've received simply state "Congratulations, your item sold and it's been paid for." It shows the item, the price, the buyer's User I.D. and a link to Shippo (which platform isn't mandatory of course). I knew I would eventually have to use Shippo but was postponing it -- thanks to ypdc-dennis for the updated rate comparison. Shippo has the best rate for Small Packet which is only a little higher than for the former Light Packet and you don't have to fill out custom slips.
Since all my items are IPR, I don't know what the "sold" e-mail looks like when payment has not yet been made.
This isn't a big issue but I'm curious to know why eBay introduced this change and who it benefits, if anyone. Anyone venture a guess?
