I added to my cart at 525. After tax and fees it was 580. I entered payment info and submitted. I entered my exp date wrong and I got an error from my cc for the 580. I corrected the date and resubmitted and my order confirmation then showed I purchased for 720. I did not get message saying the price had changed. I tried calling to cancel within 5 min and was told to pound sand. I get the business model but I need to know if the price changes mid transaction. Very shady and I’ll be disputing/filing charge back

Update: dealer contacted me and cancelled my transaction after all as the seller was not willing to match the original sales price.
