Amazon works hard to have a minuscule profit. If they have no profit, they don't have any tax liability. The business they're in lets them adjust their profits in real time -- whenever they expect to have large profit, they just lower their prices to eat it. Consumers love this, so they have huge turnover, and thanks to this, small increase of prices earns them big profit, if they ever need cash to fund acquisition, or new warehouse, or whatever.
