UPDATED NEW COUPONS: Check out this newer post for the latest eBay / Paypal coupon codes.

eBay has some rare coupons when you use Paypal to pay for your auction. One per auction only and if they do work, it will be only one time each.

Coupon Codes:
10% off (Max $25 off). Coupon Code: C-MARCH2006CAT (Valid thru March 31st)
$10 off $50+ (Fashion). Coupon Code: C-APR2006FASHION (Valid April 1 - 15)
$20 off $100+ (Technology). Coupon Code: C-APR2006TECH (Valid April 16 - 30)

Note: These coupons may not work with all Paypal accounts, so purchase with the intention to pay full amount.

UPDATE: Confirmed Not True.Some users have reported that the March coupon will only work if your account was created in March. Could be any year, 1999, 2000, 2006, etc. We haven't been able to confirm this ourselves however. You can tell which month your account was created on your feedback page.

Also it is unclear whether the Fashion and Technology coupons will only work for those type of items. If a someone finds out otherwise, please post in the forum.

UPDATE 2: Another coupon code to try is: C-MAR2006ANNIV for 10% off in March.

UPDATE 3: Check the forums for a new technique to see if these coupons will work before the purchase.

UPDATE 4: Another coupon code. Use code CPPEBAY03 for $3.47 off shipping
