In my supermarket, I can walk down an aisle and see 2-liter bottles of Pepsi products, then 2-liter bottles of Poland products, then 2-liter bottles of supermarket-brand products, then 2-liter bottles of Coke products. I strongly suspect the store brand products are manufactured at a bottling facility that also bottles other, name-brand sodas.

I think that's all perfectly healthy competition and I'm glad that the super-market offers cut-rate, easily-substituted products on the shelves that they own.

If that is good, how is what Amazon doing so different as to be bad?
