It probably costs $5 to make a decent quality canvas bag.
The best part is Bethesda distancing themselves by saying that the guy who wrote that response doesn't really work for them and doesn't express their views, then turning around and saying the exact same ing thing he said.
Guy: Bethesda won't be giving you the bag you paid for because canvas is too expensive to make. And no, you won't get your money back.
Bethesda: Sorry, that guy doesn't represent us. You didn't get what you paid for because canvas is too hard to find. And no, you still won't get your money back.
