Amazon has announced when its annual Prime Day will be, and this year it will actually take place over TWO days: on July 15th and 16th. The 48-hour event will be increased from 36 hours last year. Prime members will have access to more than one million deals on the site starting at 12 a.m. PT on July 15th and ending at 11:59 PT on July 16th. Amazon usually releases a few early promotions and deals in the run-up to Prime Day as well, which are usually related to its devices and services.
