Walmart complaint: Lack of WILLING help

I started this about 3 weeks ago, 1st time I was shopping in the grocery section and came across an endcap which I notices Frenchs Fried Onions on clearance for 1.00 and on the same endcap Idahoan instant potatoes for .50 a packet. I went to purchase a few and at the checkout, the onions rang up at 3.78, I told the cashier about this, The answer I got from the cashier is I DONT KNOW WHAT TO DO, The same thing happened with the potatoes ringing up at 1.12. Again the same response from the cashier, I left without the items, My second trip the items were still on the endcap and I picked up a few for the second time, Again they rang up wron, The cashier did override it. Well 3rd time in walmart thought I would get some more, Upon reaching the cashier Again they rang up WRONG, I explained the same thing, the inexperienced cashier called the lead cashier over and she told me she would give me 1 at 1.00 but I would have to pay full price for the other, I told her again it is their policy to only honor 1. Again I told her it is on the endcap, She said sorry, it might be in the wrong place, AGAIN I explained the whole endcap is filled with these 2 items. She would not send anyone to check nor call the grocery department.

This is an ongoing problem with pricing in this store
