i found this while searching for a code - hope it help -
WANT EBAY COUPON CODES SENT TO YOU? Read Read Read Read! THIS IS VERY IMPORTANT AND WILL EXPLAIN WHY SOME PEOPLE DO NOT GET COUPONS FROM EBAY and PayPal. In "My eBay", under "My Account" on the left side of the screen, there is an option for "Notification Preferences". If you click on this, you will be taken to a large variety of "preferences". Down at the bottom, the very last choice is "Promotions and Surveys". Click on "Show" and you will be given five "Subscription" options. The second one is "General email promotions. Send me emails about whats new and hot on eBay, great deals, special events, discount coupons and other special offers." Just put a check mark in the box, save your settings, and voila! You WILL receive coupons eventually, not right away of course, but when eBay gives them out. I know you all will adore me after this, and hopefully there wont be too much whining going on afterward.... ENJOY!!!!!
