I purchased mico wave, but can't pick date and don't want reorder it. Can day earlier or 3 days later?

Your question isn't clear to me. I'm sorry. However, I have NEVER had any problems with Best Buy ever! I norm shop @ 2 different locations. Triadelphia WV & Robinson, Pa. At both places NO complaints. Even with an older purchase w/receipt, no probs. I'm sure if u call and explain ur situation they WILL be accommodating.

You have up to 5 days after your order is ready for pick up to pick it up or it cancels

Just call them and ask
