So something weird happened to me twice recently at a grocery store.

Firstly. It's a local mid level grocery store in a medium sized city (we have 3 Walmarts, for scale).

I don't go there often because it's more expensive than other grocery stores. But it's also the closest one to me. And huge. So they do have everything. But it's not like a fancy gourmet grocery store that offers wine samples or anything.

Anywho.

I went there and bought like 4 things.

It was easy to remember how much each item was since I only bought 4 things.

When I went to do self checkout , 3 of those items ran up 50 cents to 1 dollar cheaper than the price tag.

I don't use a saver card or anything.
The 4th item happened to be a deli item. It was the price it had on it. Cause those literally have a sticker on them.

I thought. Weird how 3 items ran up the wrong price.

I go back 2 weeks later. Same exact thing happens. Different items. Everything except the two deli items I bought were pricing at 50 cents or 1$ cheaper than listed. I paid extra attention this time because of the last experience.

Sometimes I wonder if I'm paranoid. Seeing manipulation where there is none.

But this can't just be a coincidence.

I don't go there often.

I use the self checkout.

Is it using facial recognition to see I'm a "new" customer. And charging me less so I feel like my bill is lower than expected so I will return ,?

Am I taking crazy pills ?

Someone tell me I'm wrong and that theory is absurd.
