Ok... this has been bugging me for about a week and I need to get it off my chest, I hope I don't get arrested

Basically I was at a big department store with Mum last week and saw a purse on a great special and rang DH and asked if I could have it for my bday and he said yes. I didn't buy it at the accessory counter then and there though because I wasn't 100% sure if I should splurge on it (I don't generally treat myself to nice things).

Mum and I walked over to the bra section and I got fitted and chose 2 bras that were also on sale, and I took the purse and 2 bras to the counter in lingerie for them to get rung up. I also used two gift cards I had with small amounts left on them. The lady checked what was left on the gift cards, rung it all up, told me the balance, I paid in cash, she put all 3 items in a bag with my receipt and said the obligatory "have a nice day."

Anyway 10min later when Mum and I were about 100m from the store, Mum questions the amount I paid in cash as she thought it was a bit low... So I checked the docket to see if maybe the bras were cheaper than I thought, or maybe there was more on the gift cards than I realised... but no... the lady hadn't charged me for the purse......................................

I didn't go back! I feel bad! Normally I would, but money is so tight right now and the silly lady put it in the bag, she can't of thought it was a wallet I already owned, I even mentioned it to her at the counter because it was a particular brand that I wasn't sure was part of the sale...

Karma is going to be a b*tch , isn't it?
