StubHub is like eBay for tickets.  You can buy tickets to sold-out sporting events and concerts.  Using fancode (i.e. coupon) WEL040849WV3, you can get $20 off a $20 order -- a great deal.  They charge a 10% commission to the buyer and a shipping fee.

Use your American Express business card with OPEN for an additional 3% off at StubHub.
