be as honest and accurate as possible.
if it has a small mark for example say so, and try and get a pic of it.
starting price is tricky. sometimes a 99p one will be good to get interest, but then it can backfire - someone has had an absolute bargain off me this afternoon - practically brand new next jeans for 99p - i wish i had put them on higher, but on the other hand i sold some others for £12
its good fun and you soon get the hang of it.
you do get charged fees tho so be ready for this - from both ebay and paypal, but usually i just add a few pence onto postage to cover this
