It's all walmart garbage, even if it's unused. Why would anyone buy it from you, when you got it from the clearance rack at the same wommart the customer already shops at? Who cares it you price it at like a quarter or something, no one is going to bother buying it. It would be so much more trouble than it's literally worth to sell that junk.
Having a successful yard sale is actually hard work. And she has ZERO items that would sell. No appliances, no furniture, no vintage items, no exercise equipment (lol), no gardening stuff or other useful tools, no outdoors/active type stuff like bicycles, no children's toys or clothing... the only thing that might sell IF she advertised well and staged the clothes properly would be her TORD hoard... and it doesn't seem like she's getting rid of any clothes.
