From The Salvation Army blog:
For in-kind donations you contribute between April 1 and May 31 to select Salvation Army Family Thrift Stores, you will be thanked with a $10 gift certificate to any Phillips-Van Heusen, IZOD, or Bass retail stores. Participating Salvation Army stores will provide you with a dated receipt for your generous donations and a coupon to redeem for your next shopping trip.
(Thanks, Money Saving Mom!)
Cool info, Kelly! Thanks!
