Best Buy Marketplace allows third-party retailers to sell electronics and office supplies at BestBuy.com.
Shoppers can scroll through products from trusted sellers and find a larger variety of products and brands than they normally would at one store.
To get the most out of your experience, here are the 3 things you need to know about Best Buy Marketplace:
1. Best Buy promo codes aren’t redeemable at Best Buy Marketplace
Best Buy Marketplace products cannot be purchased with any My Best Buy ™ rewards certificates, Best Buy promo codes, gift cards, Best Buy for Business Cards, or store credit. However, if you’re interested in checking out a variety of products from different brands, Best Buy Marketplace is a great alternative for purchasing electronics and accessories at affordable prices.
2. Best Buy Marketplace adds 30% more products to BestBuy.com’s inventory
The Marketplace boosts BestBuy.com’s online inventory over 30% by including other trusted brands the retailer doesn’t already carry. Shoppers can search through a wider selection of phone cases, smartwatches, computers, and more, all at competitive prices.
Each product page includes a detailed description of product features, reviews, and pricing, so you can determine which item is right for you.
3. Shoppers deal safely and directly with third-party sellers for shipping and returns
From tracking an order to returning a product, shoppers deal directly with the third-party seller they purchased the product from. The Marketplace Promise guarantees safe, secure transactions (and Best Buy partners with only credible retailers), so there’s no need to worry about Internet security.
