According to the stores in Richfield MN, 1582 is the "store" number for Best Buys Corporate office located in Richfield MN. If you see a charge stating Best Buy Richfield 1582, it means something was purchased through BestBuy.com
No matter where in the country the order is placed, the charge will always be billed as Best Buy Richfield 1582 since that's where the corporate office and their billing is.
Which makes sense since my bank told me that the card number was hand keyed in and not swiped. The very nice associate at the Richfield store location transferred me to their customer service line and had me ask for consumer relations, I sat on hold for a little bit but overall not to long and they were able help me figure out what the charge was for. Hope this helps anyone else who has ran into this
