how to save $$$ on your grocery bill!

So here is how I did it. I was shopping at walmart, and checking out. I seperated out my ad matches and put them at the end so it would be easier. When I told the cashier I had ad matches, she said I had to have the ad to "prove" it. I told her that I didn't have the ad and I know that I don't have to have it. (when I do bring them in, they NEVER look at them anyway!)She said she would go ask a csm. She came back and said she couldn't do the matches without my having the ads, then the csm came over and glanced at me, then asked the cashier, "did you tell her?" the cashier said yes, then the csm started walking away. So I asked, "you're not going to give me the ad match prices?" She looked at me, rolled her eyes, and said, "no" and walked off. The cashier got a smug little look on her face and started ringing up the stuff. I said, "no thankyou. If you can't ad match, I don't want to shop here." she looked at me and said, "fine". I was so mad that they would be happy to lose a $200 sale, just to save a few dollars by not ad matching. So I went to the service desk to fill out a complaint. The girl tried to tell me that they don't have anything to fill out. I told her that I needed a comment card and I know that they have them because I've used them before. She then proceeded to put away returns and dink around for over 5 minutes. then she came back and said, "I couldn't find anything." So I said, "fine, I'll just call the market manager." I went up to the poster and dialed him right there. He was of course, very apologetic and confirmed that I didn't need the ads. (wal-mart's policy) he was a bit disturbed that they just let me walk away and not purchase the groceries. He asked for my name and #, so he could follow up, and when I told him, he said, "Oh, Rebecca. I've spoken to you before." That made me feel a little silly to realize I'm THAT person! but I still felt this complaint needed to be complained. I left and was on my way to fred meyer, when the store manager, Jason called me up. He was also very apologetic and he wanted the names of the girls I had dealt with. He said he wants me to continue shopping there, and asked if I might come back. I said I was on my way to fred meyer to shop instead. (half of my ad matches were from there anyway) He said if I would come back, he would give me 10% off my entire bill, after the ad matches and coupons. So I couldn't really say no to that. So I ended up going shopping AGAIN, and then I just got to go straight to the service desk to check out and didn't have to wait in line. They paged the same CSM to come approve the discount, and she wouldn't even make eye contact with me. she just turned her key and said a few thing to the service desk guy, and went into the office to hide. I didn't know they kept track of the people calling in to complain, but I'm glad it paid off for me this time.
