Namecheap doesn't usually do renewal coupons, unless you have 50+ domains and ask for the "GOLDDEAL" coupon to be activated on your account.
However, to celebrate a milestone on their Facebook fan page, they're releasing a renewal coupon that's
good for tomorrow, 5/24 only.
Coupon: FBRENEWAL
Valid for: 5/24 ONLY
Usage: renew unlimited domains
