Maybe I'm late to the party, but the Gap family of stores--including Banana Republic & Old Navy--offers free return shipping all of the time. So is Bloomies!
I'm just waiting for JCrew to offer it, and then I'd be a super happy camper. I've mentioned it before (and I'll probably mention it again)--I love return shipping. Favorite online retailers that offer the free return shipping service include: Sephora, Nordstrom, & Zappos.
