You can buy a Best Buy gift card below face value when a marketplace has one in stock. If you're shopping for a specific product, compare the actual gift-card discount with the rebate you could get by buying the product through a shopping portal. The gift card saves money when you buy it. A portal reward depends on the product, payment method and offer terms.

Compare both routes without assuming they combine.
