How to find a a football ticket (obv at premium) without paying some extortionate internet prices?

All I am after is a Wales - Poland ticket for myself.. Father was Polish, mother Welsh.

I am reasonably local (1 hour drive in Eng), but cannot find one at a reasonable price. I realise I am will not be paying face value, and am happy to pay more. I just want do not want to pay/can afford what some of these internet ticket sales prices claim to want.

Any ideas?
