Each time small-business owners use their “MasterCard BusinessCard” or “Debit MasterCard BusinessCard” between now and June 30th they will be automatically entered to win a $100,000 cash prize: $50,000 for their business and $50,000 for themselves. During the contest cardholders will receive double entries for any purchase made with a “MasterCard BusinessCard PayPass” or with any “MasterCard BusinessCard” at Staples – whether in store, online or via their toll-free phone number. Also there is special pricing on MasterCard customizable “Gift Cards” that provide small businesses with the ability to tailor the card with their business logo. The MasterCard “Run Your Business, LIVE Your LIFE” sweepstakes is being run in conjunction with the free Microsoft “Office Live Seminar Series” which kicks-off this week with expert advice and insights on topics critical to small-business success.
