In the shipping world, the term to describe the situation where the seller is not responsible for shipping problems after a point is “Free On Board” (FOB).
This is used in some b2b transactions, esp. at the wholesale level. It would be uncommon to see it stated in a sale to a consumer. And (this is the important point) if FOB is not in the sales agreement, it doesn’t apply.
Any seller on Amazon or whatever that presumes FOB without it being clearly stated is deluding themselves. (Sadly, there are a lot of delusional people out there.)
If the choice of shipper is the seller’s and they regular choose a crappy one, then that is clearly something other buyers need to be warned about.
Try telling the IRS that you put your tax return and check in the mail, and if they never got it, it’s their problem.
The buyer is not a bookkeeper. You are paying the seller to get a product to you, not to the delivery company. If the delivery company never shows up, or comes unreasonably later than promised, I hold the seller responsible. I also don’t buy from sellers who require me to pay extra for shipping insurance.
Yes, but not if they ship via a disreputable delivery service.
