UPDATE: I just wanted to let ya'll know that I went in to Target today. I went up to the client service desk and explained the situation to the girl there. She had to call a manager. The manager came over and he had to call someone else who didn't know what to do.
They thought it was funny that I came in and wanted to give THEM money. LOL Finally the manager made one more call to someone who was apparently the big head guy. I can't remember what his name badge said but it was impressive. :)
After thinking for a few minutes he said that it would be more of a hassle to try to fix it so to just go with it. To which I said "but that's stealing" and he replied "not if I give you permission" ROFL I was laughing. I know I'm pathetic but I have a HUGE guilty conscience and I don't want anyone to get in trouble.
He assured me that no one would get in trouble. PHEW!!! I just LOVE my Target. And so I spent another $50 today. LOL With coupons of course.
Thank you all for your help!!! Especially Pennywatcher. You just kick butt!
---------------------------
I went to Target last night after work and had a lot of fun just going through the ailse. I got a lot of goodies - including my Electrasol for $0.25 overage.
When I got up to the cashier I separated out all my Qs and put them with the items because I wanted to make sure they knew that I had everything for each Q. I figured they'd probably just want to take them in a pile and do them at the end, which is fine.
So, she rings everything up and my total was around $84.
Then she starts to put the Qs in. She takes her little gun and starts scanning them and putting the scanned ones in a pile.
Then about halfway through one of the printables won't scan. So she sets it aside in a new pile. Then I notice that a couple hadn't been taken, so she has to stop and figure out which one didn't take and press the little button.
I was
NOT trying to confuse her on purpose but I wanted to make sure all the Qs went through. Oh, and her name tag said she was a new cashier.
So I had a LOT of Qs and I said that there should be 4 x $4 off and wanted to make sure all four came off.
She then started scanning and putting the Qs in the drawer. So now she has two different systems - the pile she already scanned and the Qs going into the drawer.
THEN she starts taking the Qs on the pile and scanning them again!!!

I stopped her and told her that I thought she already scanned those, but she was adamant that she hadn't. I felt so bad because I SAW her scan them already. But she was sure and there was a line and I didn't want to hold it up anymore. The lady right behind me was VERY pregnant and did not look happy.
I think many of them didn't go through because they had already been scanned and I didn't ask her to push the button when I saw they weren't going through. But I think that a few DID. Which means double counting those Qs. :(
My final total was around $24. I had a lot of Qs, but that is still a little low. I'm thinking that it should have been around $30+.
And now I can't find my stupid receipt!!! I was going to go through it and see if I could figure out which ones got double counted so I can go back in and give them more money if needed. I feel a little sick about it because her register isn't going to balance out and I don't want her to get in trouble.
I've looked through all my bags and in my car and I'm worried that the receipt got left in my cart.
What do I do????? 
Should I call the store?
Seriously...the guilt I have is unbelievable.
