Kidding right?
On peak days Amazon ships between 1 and 2 MILLION packages. Plus Amazon processes a heck of a lot more data than the ITMS does. Really; storing this much information nowadays is peanuts. The "snooping" is done together with Akamai, who can easilly deal with the couple of million customers the store has.
Amazon is in a totally different league than the ITMS.
