For those of you who remember, njlf and I used to organize Secret Buddies. I haven't done one in quite a while. First of all, I had some serious health issues so I took a break. Besides that, we frequently had people join who didn't send their packages out (but gladly accepted one). Honestly, it just got to be too much.
I found this group:
Swaps N Wishes
The link gives you a sneak peak, but you have to be a member to see everything.
I've been there for over a year and really like it. You post things (new or used) that you don't want, and you get "credits" to use to "buy" other things. It's a great way to get rid of things you don't like/use and get things for yourself and for gifts. You do pay your own postage. There are also seasonal swaps, auctions, games, etc. They are in the process of opening a children's swap section.
Please PM me if you are interested in joining, or have any questions.
