I've been selling (and buying) by mail order, and usually allow 20 days for arrival from North America before complaing. Usually things arrive before that, but not always. And I allow 30 days from Asia.
Remember that wherever it is shipped from, your item is too cheap for the buyer to afford to include international tracking.
Seller has his shipping location listed as the US but is based in China and says it will take 18 - 28 days to get here.
It's a bit unusual for an Asian seller to be dropshipping from the USA, but not impossible or even rare.
Were there a lot of complaints in the seller's feedback about slow delivery or saying that shipping was actually from China?
Basically, you may or may not get any shipment that does not arrive by June 30, no matter where it originates, because of the Canada Post labour situation which puts the union in a strike position on Saturday.
This is not in any way the responsibility of the seller.
If the item has not arrived by the deadline eBay gave you, then you can open an Item Not Received Dispute.
I actually am baffled at why people buy these cases by mail when they are available at every mall I've ever been in. I suppose if you live in a rural or remote area or are disabled.... but it's not the sort of thing that is a necessity and needs to be receive toute suite.
