MasterCard has launched a Web site where cardholders can gain access to deals and discounts from thousands of retailers and manufacturers.
The card giant's MasterCard Marketplace is based on technology from e-commerce and advertising technology specialist Next Jump, which claims to have "created the most powerful technology engine for sales, achieving the highest conversion rates of browsers to buyers".
The site offers customers who sign up discount offers from 25,000 participating retailers, based on their merchant preferences, ZIP code, and Web site activity.
Users that find an offer they like are then given promotional codes or coupons to be redeemed online, over the phone or in store, depending on the merchant. Customers can also rate the offer and write reviews of the merchant.
