Didn't sell me product for price I saw.

Last night I was trying to do some online shopping. I went to the sears.com website and searched through the ad. I flipped to pages 6-7 on the weekly ad and found, on page 7, a Panasonic 37" class Full HD LCD TV on sale for $799.99 (with extra discounts once clicked on). After clicking on the TV the price showed $799.99 on sale. Plus $200 instant savings, plus 5% discount for V.I.P. Total savings $400. Which brought the price down to $399.99. Online it said that the SALE was for in store only 16th and 17th of November. So this morning I sent my husband to the Woodbridge Sears and, to make a long story short, they told him that they would not give him the TV for that price because it didn't cost that. They told him it cost around $1200 and that the total savings was already taken off the price, reducing it to the $799.99. On their ad there was no mention to the $1200 and it did mention both those savings. I know my consumer rights and if I had gone instead of my husband I would have fought for it because they were making false publicity. My husband doens't speak 100% english and I feel they took advantage of this point in saying he misunderstood the ad. I don't know what else I could do. This was not a correct action from them. I already purchased my refrigerator and washing machine with them and did plan on making other purchases. I'm very dissapointed. Can you please tell me what I can do!
