I don’t know why everyone (not you) is acting as though this was some “ridiculous” amount of weight for a bag? It’s about the same as a gallon of milk, a couple of roasts, OR a 6 pack of beer.
That the bags that WAL-MART’S purchasing department chooses to buy are so flimsy or poorly constructed that they cannot handle such a light load is ridiculous....but then, they have a culture of buying “cheap crap” so it’s not that surprising.
Do they not have some culpability?
