I'd send the guy a message at this point and possibly even threaten to open a case on PayPal and eBay if they don't ship out.
250$ is not a little bit of money
well I found out I wrote an eCheck and have to wait for the funds to clear (haven't used my paypal in 3 years o.o). So...it's probably not going to get here until sometime at the end of next week if my predictions are correct
