Financing Terms: Online orders can be split into monthly payments through Affirm financing. Standard credit card financing plans are not offered. App Quirks: The web system lets you buy items with a MasterCard credit card. That same card type will fail if used at physical store registers. In-Store Payments: Warehouse registers and gas pumps exclusively accept Visa for credit card transactions. MasterCard or Discover credit cards are blocked in stores unless processed as a PIN-debit.
