On sale price in the store might not be the best price

I spent so many hours shopping for appliances around home depot yesterday. Here are the model # OF the appliances that I like: JGB918SELSS; LFX25960ST; WM2233HW; DLG3744W; LDS5811ST. As soon as I got home, I got online and typed in the model numbers of the appliances and compared the prices. Home depot is offering 10% off. Fortunately, the price of their refrigerator is $1,000 less in their website. I called the sales rep and told him the difference of their price online. The salesman asked me to print out the page and bring it with me when I go to their store and I did. He can’t believe it but since it’s advertised on their website I got the refrigerator way cheap and they also upgraded me to the next model of the GE Gas Range because the item that I liked is out of stock. Not just that, we also got $600 rebate. I’m just so proud of myself today ;-(
