We all would love to save money on things we want to buy. There are plenty of price alert tools that can keep track of prices on Amazon and other stores. The Woo Price Notification/Alert Plugin lets you add such a feature to your website. It enables your customers to sign up for price notifications on your site.
You can use this plugin to update customers on changing prices. Your customers simply enter their e-mail and desired price and the rest is easy. Admins can customize form labels, buttons, and template.
