I'm offering up podfic and mail.
While I'm pimping, here are some things friends of mine are offering:
kronos999 is offering book binding services (we have some of her books around the house and they're pretty awesome. I just stick my printed off fanfics in a binder but she makes them awesome)
seanchaidh is offering up fic
takhys is offering hand made earings
They have a master list of the types of things being offered here. Or you can check out their delicious account.
Bidding ends August 28th @11:59 EST
