Keep getting your order cancelled because they are unable to verify your information and you KNOW it's not your card....DO THIS!
I had more than one shipping address and that was linked to my billing address. Remove all but the correct shipping/billing address by doing the following:
Go to the BestBuy home page.
Click where it says Hi, your name!
Under Manage Your Acccount select Shipping addresses
Remove the additional addresses (even if they are identical or close)
BEST BUY. You SO OWE ME. I would like a new fridge, stove, dishwasher and microwave for my kitchen lol
