Target scam???

I don't shop at target often so I'm not sure if this is just something I had trouble with or whatever.

The last two days ive gone to check out and multiple items were totally different prices than what was marked on the price tag.

I had gotten an item that said it was $10 but rang up as $50!!!

Then another that rang up $5 dollars more than posted.

The first day it happened they had to go and look on the shelves to figure it out and I was right.

Today I took a photo of the price tag on the item I bought just in case this happened.

Now, target is very good about fixing this if you point it out but I wonder how many other people this is happening too and they're not noticing
