Shop a lot at WalMart.
They have the flimsiest bags of any store I’ve seen. This purchase should have been double bagged — or in multiple bas.
This guy may have a case.
Their bags have holes in them when they are NEW. I’ve had things similar to this happen to me there. IMO this case should not be dismissed lightly. Maybe the answer will be BYOB.
Try a Lowes bag for flimsy.
