Work from home does it exist?

What is work from home ? Can you find really work from home or are they scam ? I was trying to find work from home ,so I can still take care of my kids ,searching day and night for a work on line. All the jobs available that I find there was a fee to pay all of them are about £29.99 one fee payment with refund if the programme is not for you ,I end up paying some of them to trying them out. The job was not for me so I send an e-mail for my refund that I had back. Few days ago I find another work that again I had to pay £6.99 for the training to start working as a typist and Data Entry from home. When I did see £6.99 one time fee but NON REFUNDABLE I taught to myself that £6.99 for training is not expensive .I paid my fee and two day later still did not receive my training . I did send lots of e-mails to the person that I did buy the training for, and at last I had a reply with the training ,I was very exited to start ,so I went to start my training thinking I am going to find agencies that I can replace ads for .Well it was not what I expected cause all the work it was not data entry ,or filling ad forms for companies it was like a pyramid scheme , have to put the same advert on lots of free ad sites with all the false promises that there is a work from home as a typist or data entry available ,so people buy it and then they have to sell it back to other people promising things that don’t exist. It is a scam. I spend my money because it was believable saying “this is not a quick scheme, you get paid it depends how much time you put in “. It was a different ad from the others it was very believable. SO never pay for work from home. When there is a fee most of the time is a scam .
