Anyone bought S&P Probability Trading Strategies Manual

It comes from spdailyanalysis.com and is adverstised on this forum but is quite expensive (595$). Despite the price the publisher offer a 500% refund guarantee andclaim the SP trades are 65% accurate.

I get a free email from here every day:-

That refund seems a bit dubious. Make sure you read the small print before parting with any cash.
