I give most mine to family and friends as 'stocking stuffers' and the like. I also gave some to my Mom who sold them at her Catholic Charities Gift Shop (probably for 50 cents a piece) and she claimed that people loved them. My friends actually love to get them as the cases make nice travel kits. I keep a couple in reserve.
I would go the charity route - selling them on E-Bay is probably more trouble than they are worth.
Now, the Christian LaCroix pajamas I got on AF - those I keep for myself!!!!!!!!
