How to save at Best Buy (the price match is the lever)

Electronics pricing moves constantly, and Best Buy's price match policy is worth more than most codes precisely because of that. If a qualifying competitor lists the same item lower, the policy is designed to meet it — which means the lowest advertised price anywhere is frequently available without a code at all.

1. 1

   Check competitor pricing before you buy

   Find the lowest qualifying advertised price on the identical model. The policy exists to meet it, which makes the search more productive than looking for a code.

2. 2

   Watch the post-purchase window

   If the price falls shortly after you buy, the policy generally covers the difference within a stated period. That requires you to notice, so it is worth checking once after purchase.

3. 3

   Compare open-box against new

   Open-box items are graded by condition and listed separately at lower prices. On large items the gap frequently exceeds any promotional discount.

4. 4

   Check membership benefits before paying

   The paid membership tiers carry their own pricing and extended return windows. Those attach to the account rather than being entered as a code.

1. 1Reveal and copy a Best Buy promo code above, then paste it into the discount box at checkout before you pay — the price should drop straight away.
2. 2Percentages on this page span 10% to 35% off — start with the largest and work down, since the biggest discount often carries the strictest conditions.
3. 3Compare offers before you buy: a percentage-off code like 35% off usually beats a fixed-amount code as your Best Buy total grows.
