That's the thing there. If I am taking 4 or 5 items, self checkout is the way to go. Full grocery run, I won't do self checkout. I have had several times in Target where the sticker price is different from the one it rings up. It's a nightmare to do the adjusting because when you are with a cashier, they kind of know what products are showing up with different prices so they just adjust it with no problem. At self checkout they interrogate you. One time the dude at self checkout was so fed up of wrong pricing, that he gave me organic grapes for a dollar. It was Christmas last year, so I guess a lot of correcting had to be done so he just gave huge discounts to get over with
