Some users have preferences regarding which carrier they'd like to use for their shipments. If possible, allow orders to have the option of choosing FedEx, USPS, or UPS.
The last shipments sent to me were using UPS, and even overnighted, they arrived a week late. My experience with BestBuy.com has been positive, however in the future I'll be less likely to order due to the forced use of UPS for shipments. I'd much rather pay extra to use FedEx or USPS.
I don't expect your preferred carrier to change overnight, only for the option to be opened up to the customer.
Thanks for the suggestion, and I would love to hear from others as to whether or not we should put this option into place? Make sure you vote for an idea if you like it.
