Noooo, why would you want to do that. When you joined did you not have a 0% feedback?
eBay spends millions on ads look at the current tv ones to entice peeps to their site. Cancel the order and you'll receive a damaging defect on your account, it doesn't take many for eBay to ban you from the site, eBay do not like disappointing their buyers.
The buyer may have joined eBay just to buy that one item or joined to begin a buying spate on eBay.
Once eBay tell you the buyer has paid you must post the item to the name and address eBay provide on the order details.
