Just about every serious seller on Amazon has a website or another direct sales channel. The bigger ones will even ship with a professional warehouse in about the same time. Some even give discounts or return incentives if you shop them regularly and can almost surely handle customer service or tech issues faster and more directly without going through Amazon. If they are honest in their dealings their return and exchange policies may even be better too.
Amazon really understands the lifetime value of a customer and benefits tremendously by having the biggest catalog in existence. They do a lot of stuff to keep buyers satisfied and sellers on edge. It’s a race to the bottom there and nobody wins except Amazon, while customers get cheaper and cheaper shit and sellers can have their livelihood and the funds to pay the salaries of their staff by a Monday morning email which could come after the slightest infraction.
This gives me an idea for a browser plug in that would show you the sellers direct store as you shop Amazon. Maybe something like that exists already.
