its ur choice r u gonna do free shipping or buyer pays shipping.if u do free then u get alot more bids and usually bidds go very high.but if u choose buyer pays shipping then u can go to usps.com and see about how much the shipping will be...my zip is 32250...u can go and check :). or u can use flat rate boxes too(but those r only good if u shipp more than one item etc). usually shipping is only few $ on clothes-cuz its by weight...hope i helped u lil bit...if not or u wanna know something else then just ask :):)
the person bidding on this would pay. they can use paypal, money order or cash and other. lots of people use usps flat rate boxes to ship items out. the post office has the boxes there for free. i hope this helps you.
given that this is a dress, it would be easier and cheaper to send it flat rate, you should be able to just fit this in the flat rate envelope, for like $5.00
but if it's a light weight dress and the buyer doesn't live all the way across the country, it'll cost less than 5, sometimes the flat rate boxes aren't worth it... I think.
