Well, I didn't know that. For me the cheapest offers are 493.37€ for OKPay and 505.85€ for a SEPA bank transfer. As the current market price according to BitcoinAverage is 495€, these are quite fair prices. And don't forget, if you had some succesful trades and good ratings before, you can start an offer by yourself. This often results in better prices.
It seems like we have some wuite different price situations here. Well, I'm satisfied with LocalBitcoins, so I will keep using it.
The best offer is around 541 Euros for cash and 603€ for national bank transfer in this side of the EU.
I know some people get better deals but not me here .
I'm better buying at stamp.
