I made a big mistage and will never do it in future,
In a big retail chain store, I switched a clearance sticker of one item to the other clearance item, the difference was just a couple of dollars (i know very very stupid of me) but the cashier noticed the stuck on tag not belonging to this item and asked me if I wanted to buy it at its original price I said I dont want it (now I think I should have just bought it at its right price). I paid for others with cc, just then I remembered that I wanted to buy two more items as I had coupons for them, so I went back again to get those and meanwhile there were two three other cashiers(possibly with the manager) discussing and looking at the switched tag of the item that I said I didnt want. During this second transaction another cashier was there all the time looking over what I was buying for how much, he was also suspicious of my coupons but they were all legitimate, After I paid with my CC, this second cashier printed another copy of my receipt from the register and also took away my coupons with the copied receipt with him. I am hoping it was just to evaluate my coupons. But it could be for something else too.
I am freaking out as to they may go through the surveillance and try to pursue me from my CC, but if I have not bought that item can they actually charge me just for switching tags? during the first purchase I also switched tags of two more items but got afraid and removed them before they were scanned. I am not sure how much of switching they have on the video, may be my whole trip, but eventually I did not buy anything wrong, everything I bought was at the right price and with legitimate coupons. I will not go to that store for a long time and will not do such a thing again, but I know they will definitely go through it as there were not many customers so they had all the time to look into it and the second cashier seemed very keen on pursuing it.
I am very scared and cant focus on anything.
Can someone please let me know if I am legal trouble at this point? what can I be charged for?
thank you all in advance.
