[mamadiva]

I'm finally selling my Buggysnuggle.

Give some of your bestest ever tips

To BIN or not to BIN

How low should I go with reserve

How do I figure postage

How much should I actually write on the description?

HELP!

write as much as you can in the description, look at what other people have put for postage to give you an idea how much it will be to post.
as for the reserve, i dont think you can put a reserve on anything under £50
just start the price at what you would like for it, or take a chance at start it lower and hope to get more people interested/watching it.
