Im trying to grab a new TV for the guest room before my sister gets here on the 22nd and the prices on Walmart.com are literally driving me insane right now. I have been refreshing the page every couple hours and it feels like the numbers are just jumping all over the place constantly. Right now I am torn between getting the Hisense 65 inch U8H which is sitting at like $698 or holding out for the Sony X90K that is currently $899 but I have seen it lower before. My absolute max budget is 800 bucks so the Sony is out of reach unless it drops again soon. I am really worried if I wait for the Sony to hit that magic $799 price point then the Hisense will sell out or go back up to its normal price and I will be stuck with nothing when she arrives. I swear I saw the Hisense for $640 yesterday but then it went back up before I could even click buy. Does Walmart use some kind of weird tracker that raises prices when they see someone refreshing a lot? I need to know if I should just pull the trigger now or if there is a specific time of day like midnight or something when they update their holiday rolls. How often do these online prices actually change during the peak holiday weeks?
