Nemoandthefishes, look in your phone book under 'dress agency' ring them up and ask if they take childrens stuff.
Then you wash and press every thing (seasonal), take it along, what they don't think will sell they just give you back straight away. They do take a 30 or 50% cut usually but the stuff GOES if its any good, or designer/next etc. I just think that its a lot less hassle to flog a batch of clothes this way- selling kids clothes on ebay is hard unless they are bnwt or designer. And buying clothes from them is far cheaper than ebay as there is no postage! (Sorry bit of a hijack there)
By the way people, that petition and the info about the changes relates to EbayINC which is the American one. If the changes were also happening on the UK one we would all have been notified via ebay messaging in our ebay accounts.
So no need to worry about the feedback changes and increased fees for now eh? If everyone boycotts the US site for a week or leaves altogether then ebay may think twice about making the changes here.
