Mine just has to see the receipts

I admit two weeks ago I got a package from Tower Hobbies... Well it was just a bunch of small parts misc stuff but everyone knows how fast that adds up, anyway there was like $100 in parts. So we are watching TV and she asks me nicely how much were those parts?.... I replied like $40 lol, well aparently she read the receipt from the box cause she knew EXACTLY how much it was. I figured she saw the prices on the parts packs, but nope cause I tried to tell her that those prices were MSRP's and were all high prices. Now my packages have to go through "customs". She was more disturbed I lied to her than the price, so my advice TELL THE TRUTH. She got a kick out of it really, she picks on me about it now.
