I just got the Barclaycard Arrival Plus World Elite MasterCard. Having that card, gives me access to Barclaycard RewardsBoost. This site is similar to the Chase Ultimate Rewards mall, in that you earn extra rewards by shopping through the site at participating retailers.
The way it works is as follows:
Visit the Shop Online section of the Barclaycard RewardsBoost mall and click on any offer, product or online store. The site then takes you to the store’s website to complete your purchase. The store will confirm that you made a purchase. Then Barclaycard posts the Barclaycard rewards you earned to your Barclaycard account and sends you an email to let you know. Happy shopping!!!!
