I,ve got around 600 commercial systems and 99 % would be useless backfitted rubbish with illogical rules such as LS within 23 days /2nd LS within 47 days /3rd LS within 83 days etc etc.
Most from one source have between 18 and 25 bets per Year and claim they turn $300 betting 3 % into 200 - 300 thousand
I didn,t pay for any of them thank god as some time ago a number of us used to swap system rules around.

As Dennis G says there sold to the greedy and gullible.

My advice .Use FREE ratings available on the web.

One I particularly like though I post the selections under" darkys Infallible Dazzlers."
I wont post the rules as I promised the author not to divulge it,

Cheers
