Obviously, there are some very helpful WSO's and some not so great.
If you have been reading the WSO section no doubt that you have encountered type of WSO's in the mentioned price range which promise complete newbies with no skills big passive income within next 30 days.
Most of us here know that an average inexperienced starter doesn't have the capabilities or resources to pull that off with using just the system he bought in an average WSO. Yet,looking just at the reviews, one could conclude that 99% of such WSO's are the real deal.
The truth is, someone who is starting from scratch can use a product like that to get the basic concepts. It is a good starting point.
The thing is, much more than that is usually promised in the sales letter. Some of the more experienced marketers have said "Well what do you expect for $7?". I completely agree, I just think it is important that what is promised in the sales letter equals what the buyer actually gets when he buys.
