Prime Day promises big deals and discounts but shoppers remain wary

Amazon Prime Day is a two-day shopping event for Prime members promising major discounts and deals on popular items.
Some shoppers have voiced disappointment with Prime Day deals in recent years, though tools can help find good deals.
Discounts are available now on some items like AirPods, and other retailers are offering sales to compete with Prime Day.
Amazon offers exclusive 'Lightning Deals' and invites only certain members to some offers.
Coverage of the best tech and other deals will be available as the event runs July 11 and 12.
