Lots of ups anddowns, but this is THE one:

I have tried lots of sites, rev-shares, free and paid programmes but lots of them proved to be a good try but not really good. Unfortunately lots of scams, too. Very often a site would have a pay pal option only to show that it was just a way to be able to stop the programme, delete all you have done up to that point and then take all you have earned and start anew. But MerchantShares is not one of them - solid, responsive, reliable investment site with an instant withdrawal and serious, responsible admin.
