Price Match Extension allows you to place a Price Match Request button in product detail page and lets customers send you a request about lower price on the same product in other stores. After customers submit their request, you can review it, view the item in competitor's store and decide to give customers a discount or not. If the request is approved, a coupon code will be generated and sent to your customer automatically. For backend features, you can view all price match request from customers with all necessary information to approve or reject. Email will be sent to customers automatically when a request is approved / rejected. Also, you can configure the module to display the price match request form in Ajax Popup or separate page. You can allow it to create and send coupon code automatically for approved requests as well.
