Restocking fee? That is unheard of. I returned a nikon lens a few years back (after 2 weeks of use). The sales guy had to get approval from his manager, and gave me a hassle "now we had an open box item", trying to make me feel bad. But, there is no such thing as an open box lens. I was not too pleased because of that remark.
Last year, my daughter bought a Pany LX3 P&S. In a week's time, Pany announced a new replacement (LX5). She returned it with no questions asked.
So, it seems to me that it all depends on the salesman.
