Although its very easy to setup amazon.com stores, its a hassle to get paid out, if you are not in the US. Many of my site visitors are in the US, so UK version does not cut it. Some issues: - amazon will not pay to your bank if its not an US bank - amazon will pay you in gift certificates, but it can be hard to use them depending on where you are. Also gifts certificates means getting paid out in products, not money. - amazon can pay out in cheques, but you may have difficulty cashing that, depending on your location. - if you change your email address, you will loose any unpaid earnings. - if gift certificate emails do not arrive, they advise you to change your email address, without alerting you that you will loose all unpaid earnings - commission is very low. starting at 4%. Compare that to clickbank or commission junction.
