How Long Does Npb Stay On Your File?

[Pete S]

Last year (8th nov) I had a dispute with a guy over 3 records I won, he tried to charge me £3 postage for each of them and wouldn't combine the postage (so he was charging £9 instead of £2.50) so I refused to pay for them and got 3 Non Paying Bidder strikes against me.  Does anyone know how long these stay on my Ebay record?  It stops me from bidding on some items if the seller has stressed no NPB's, but it's been over a year now...
