Price Match Guarantee
AVLeaderz Cares! We are dedicated to offering the best value to our customers, always. We will match the price, at the time of purchase, on a Price Match Guarantee product if you find the same item at a lower price at a qualifying online retailer or at a local retail competitor's store. Here's how:

  • If you find a qualifying lower price online, call 1-866-859-0896 and provide a customer service agent the web site with the lower price.
  • On qualifying products, AVLeaderz will verify the current price to complete the price match.
Exclusions may apply including, but not limited to, items sold by Marketplace vendors, competitors' service prices, special daily or hourly sales, and items for sale the Sunday before Thanksgiving Day through the Monday after Thanksgiving. More Details
