um only history I have in sellin stuff is with Partylite I guess, although I suppose I sell stuff everyday too... mortgage deals at work, 'better' ideas to my daughter, and 'why I need this or that' to my hubby ;)
Payment policy
paypal (which accepts credit and debit) and check or money order
Shipping information
I don't really have a preference, up to how the person bidding... how soon and how much they are ok with :)
Return policy
all sales are final, only cause I don't want it back, haha... if there's some kind of problem though, certainly returns and refunds may totally be in order! :)
