Starting March 1, Amazon is moving away from a volume based fee structure and moving toward a category based fee structure. In other words, you'll get the same rate whether you sell one product or one million products, but you'll likely get very different rates depending on what types of products you sell.
Unfortunately, the actual rates that Amazon will be giving haven't been announced, so I don't have any information on that. That said, Amazon Associates in the UK already gives category-based commissions and you can see their rate card here: https://amazon-affiliate.eu/en/about...ertising-fees/. I'm not sure how closely aligned the UK and US rates will be, but I'd guess they'd be somewhat similar. I suppose we'll find out soon.
This may well be good news for those whose volumes are low, but it's likely going to really hurt businesses like mine that easily hit the maximum volume-based rate of 8.5% every month. How each of us should respond will depend on what we sell and how much we sell, though on our end we've already started making plans to de-emphasize Amazon or perhaps even to eliminate it completely within our portfolio of revenues.
Anyway, sorry I don't have more info right now -- the actual rates should be announced sometime mid-month -- but since I didn't see anyone else talking about this here, I thought I'd at least share what limited knowledge I have.
