Overs & Unders foreign games ??

I dont normally have such bets, but tried one this afternoon.. went into a Billys shop, picked up a coupon for the highers & lowers.. only to find that there is no prices on them.. how can they expect people to have such bets without knowing the prices ,??.. anyway I was only having a small bet & a total guess up, as it was only foreign games left.. I picked out 4 games for a £30 acca.. thought it would win about a 200/250 ish... when I got my slip back it said I would Kop 825 if correct.. this seemed incredible but on my slip some of my selections were 7/4..2/1.. ev..4/6.. I never knew you could get 2/1 type prices in unders & overs .... mind you it went the same way as all accas I had 3 correct & a greek team called Veria Fc who could only win 2-0 and that was in the 48th minute........ F...ing Form !!!!   I have e-mailed billys for an answer as to why they are witholding the important information such as prices from their customers... I wonder what rubbish they will Spout.
