You might try calling Staples, HHGregg, and Office Depot (all carried the 16G originally) and see if they have had any returns of unwanted gifts. Some returns are happening because the headphone jack doesn't seem to work.
I returned my first one because I couldn't get the headphone jack to work. The second one wouldn't work either. Turns out you have to really push hard to get the final click in place. So the second one is good and the first one I returned was probably good, too.
