Walmart has launched its own summer sale event to counter Prime Day. Only some deals are actually worth grabbing.

Apple and Samsung products are just some of the incredible tech deals offered during Amazon’s four-day Prime Day sale event.

A record $23.8 billion in sales is expected to be spent by consumers for Amazon Prime Days, Adobe said in a forecast released on July 7. That's a 28.4% increase year over year and $9.6 billion more than the comparable period last year. Last year, shoppers spent $14.2 billion during the two-day Amazon Prime event, according to Adobe.
