Financing Terms: Online payment installment plans are processed using Zip or Progressive Leasing. Long-term promotional finance offers require a My Best Buy credit card. App Quirks: The web system blocks combining standard credit cards on a single order. You cannot mix a credit card with PayPal, Apple Pay, or prepaid bank cards. In-Store Payments: Registers accept physical cash, checks, and contactless mobile wallets. Digital PayPal barcodes can also be scanned directly at the counter for store purchases.
