what do you all think, i think scam

basically, sold some stuff on ebay, now the winning bidder lives in germany, so he e mailed me sayin please post to my mate in UK who will in turn pass on to me when he visits,

so i then get an email from UK guy askin for paypal address,
why does the german not just pay me

its only 10.50 for a map sensor,

what you all think, maybe im paranoid
