There are hundreds and thousands of auctions on ebay telling you:

"you will get rich if you do this"
"a millionaire in a year"
"want to be as rich as me? well now you can!"

Many people know these are all just scams.
But if you are thinking of bidding for these, then here are some reasons not to:

1. Why would the person be selling the idea on? Surely the seller would have tried it - and obviously didnt work!

2. Youre giving your hard earned money away for an ebook, that usually has 70 pages filled with rubbish.

I once bought one of these money making ebooks, as i was rather curious what it will say.
The seller bragged "no postage rates" as it will be sent through email.
When i recieved the email, it was 88 pages long, and the first 30 odd pages were telling me what to do. It was as useful as a chocolate kettle!

Remember, they always say you will:
"get rich quickly"
"hardly any work"
"no selling or buying"
"no cold calling"

So ask yourself - what will you be doing!?
