> Amazon is rarely the cheapest way to have a package delivered to your home in less than two days. You can often find people much cheaper if you don’t mind waiting a week or two.

But "waiting a week or two" seems directly at odds with delivered in less than 2 days. End users don't really care about shipping speed per service (unless it's a perishable or temperature-sensitive item). They care about how long it will take to arrive from the time the order is placed.
