Advice please

A good way to do some research on the market value for a bag, since you're buying from ebay is to search for completed listings of the bag on ebay. That way you're looking at sellers of a bag from the same place...

Search for the name, then on the left hand side, tick off the box where it says "completed listings" , click show items.

Not sure if this works: http://search-completed.ebay.com/se...1&catref=C6&a14=-24&a56=-24&sadis=200&guest=1

Of course, personally, how much it is and how much i'm willing to pay for it depends on the condition of the bag itself!
