I imagine this is the case with most, or all, stores. Anytime you purchase something online, you can return it at their store. But I guess it all depends on that particular store.
I actually have to do a return today for something I bought online, but realized there's a store in our area (which I didn't know about), so to save on return shipping and the wait of the refund on my debit card, I'm just going into their store for the return. Much easier.
