this makes no sense.
how can you 'accidentally' click on 5 identical items, click on 'bid now' 5 times, type in 5 bid amounts, confirm them 5 times, be told you are the highest bidder 5 times, win all 5 items, get 5 emails, pay 5 times, input your paypal details 5 times, confirm payment 5 times, receive 5 receipts - and still claim it was an accident?
sellers will not post an item until it is paid for..
i think perhaps it is you who is cooking up an idea for a scam and looking for information....?
