I need to vent about brainless merchants who make changes on their sites or in their tracking systems that break affiliate links.
Grrrr...
When something needs to be updated on their site, a savvy merchant will take care to make sure that existing affiliate links stay functional or at least get redirected someplace intelligent.
And, if that is truly not possible, a savvy merchant will let his/her affiliates know that updates are needed.
Broken affiliate links are bad news all around.
Grrrr ...
