Amazon (AMZN) - Get Report has vowed that the second annual "Prime Day" will be bigger and better this year, with more than 100,000 deals worldwide available exclusively for members of the online retail giant's Prime subscription service.

Other retailers looking to piggyback on Amazon's sale day in hopes that online shoppers might also veer to their Web sites to cash in have launched their own deals and summer sales.

There is still plenty of time to take advantage of the other sales we found.
