I have seen all sorts of 'make money from the web' schemes, normally ones that my wife shows me while she is looking for get rich at home tricks.
So far, I have not found a single one that would be worthwhile for a decent return. There are some, like Valued Opinions (you can look it up on the web) that pay a small amount per survey, but you are looking at £1-2 for 15-30 min surveys. Nothing that will make the bank manager grin with glee.
There may be others, but I haven't seen them.
I do actually use Valued Opinions, but it pays a tiny amount. Just something to add to an Amazon account over the year to make a tiny dent in Christmas present costs.
Hope this helps...
