MasterCard users get an ability to shop online with MasterCard Marketplace

MasterCard introduced a new Web site, MasterCard Marketplace, that enables cardholders to gain access to deals and discounts from thousands of retailers and manufacturers.

The new online shopping mall is based on Next Jump’s e-commerce and advertising technology, calming "created the most powerful technology engine for sales, achieving the highest conversion rates of browsers to buyers".

MasterCard Marketplace offers consumers 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.
