Although it may seem to the outside observer that Amazon and eBay are in the same line of business in actual fact they are as about as far removed from one another are they could possibly be.

• On Amazon most traders sell Amazon products.
  
• You cannot sell eBay products (there is no such thing).
  

On eBay sales of motor vehicles and properties are just about the highest of any company in the world.
Amazon and eBay are totally different from one another so it is quite reasonable to select both to trade through (please notice that I said trade though and not trade with).
To trade through either of these companies is reasonable easy and there is no reason at all why anyone working from home should hesitate to select other companies to work with as well.
Both companies Amazon and eBay work with a multitude of other companies to make life easier for themselves with services such as product suppliers, dropshipping, statistics, postage etc, there is no reason why you should not either.

1. Do not get either Amazon or eBay confused with the get rich quick schemes which we are all are used to seeing online everyday now.
   They are both massive business run for people like us to both buy and sell through.
   
2. There are online courses that you can buy that claim to teach people how to use both systems, common sense prevails but avoid false claims if you can.
   
3. Avoid exaggerated claims such as 'I made $150,000 in just one day, you could too' (or you could just email them and ask them for the details and just say that you just want to check those numbers out with the tax man?)

One of the main reasons that so many home based business's do not seem to work is very easy to explain, it is this: In many cases they do work, but the people that buy into them are lied too in the very beginning and their expectations are simply not met.
My advice is this, if you see an opportunity that you like, check it out properly, how long has this person been in business? what can they do to help me? do not give them any money at all, forget about their guarantees.
Is this the sort of business that you really want? Could you do it? This ones important, will it be fun? Please do not do something that you are not proud of and that you are not going to enjoy, life is too short for that.
My old slippers.
Yes that what I call this last one.
Have you ever gone out with a new pair of shoes on and then found out that they hurt your feet? And then when you got back home you sat down and put your old slippers on? Didn't it make you feel good? Well that's what you really want to aim for here, just treat the next opportunity that you look at as you would your old slippers.
And If it don't fit, don't wear it.
