Selling used children's clothes
Firstly, ensure you check all items thoroughly - are there any stains, pulls, holes or pilling in the fabric? If so, you can still list it but you must tell bidders the exact condition of the item - no one likes to feel they've been fibbed to about the condition of something they've bought, even if its an honest mistake.
Second, try to combine items - bidding prices usually go higher if the buyer is getting more for their postage dollar.
Third, offer a postage discount - final bidding prices are greatly affected by postage costs.
Lastly, list clothes a low bidding cost but only if you don't mind risking you'll get only one bidder and have to sell at .99c
