A question for players please, in relation to "Lucky 15" stakes.?

Are they "Lucky 15" value bets good for us players or are they a good thing for the betting shop. Yes I understand that if we could win, not be there. But you can have a good relationship money and the value of bad game for gambling money. Thank you.

I bet the lucky 15 `s, i get the chance for a winning treble, 5 / 1 is your money back … that `my new favourate bet. Small returns big bets if you have 3 or 4 winners (in terms of probabilities) i took the runners Bet of £ 10,000 five years ago with a set £ 7.50
