Shop on Amazon and save up to $183.61 extra

Casper is possibly the biggest home-related buzzword on the internet right now. The pioneer of the mattress-in-a-box trend doesn’t do sales often (because they don’t need to), but it’s offering 10% off this week in honor of Casper’s 10th birthday. Aw.

That seems like a steal until you realize that Amazon is literally celebrating Casper’s birthday harder than the company is: Making your purchase on Amazon can save you up to an extra $183.61 compared to Casper’s sale prices — plus Prime shipping.

For example, adding a queen-sized Essential mattress to your cart and using code SPRINKLE on Casper’s site brings the price to $715.50 (originally $795). On Amazon, a queen-sized Essential mattress goes for $600 flat. 

Here’s the full price comparison after the 10% discount on Casper (mattress only, no bed frames):

• Twin: $350 on Amazon vs. $405 on Casper (regular price $450)

• Twin XL: $400 on Amazon vs. $450 on Casper (regular price $500)

• Full: $500 on Amazon vs. $585 on Casper (regular price $650)

• Queen: $600 on Amazon vs. $715.50 on Casper (regular price $750)

• King: $711.39 on Amazon vs. $895.50 on Casper (regular price $995)

• California King: $683.46 on Amazon vs. $895.50 on Casper (regular price $995)

Honey, that’s what I call investigative journalism — er, shopping.

Throwing back melatonin or a drop of CBD oil may alleviate your sleep troubles for a few nights, but nothing replaces the physical aspect of a quality mattress. Instead of rigid box springs and a worthless topper, the Casper Essential mattress supports your body with three layers: The top is bouncy and prevent sweat, the second minimizes pain by cradling pressure points with memory foam, and the third reinforces the top layers and ensures use over the years. 

Regularly $450-$995, you can save up to $183.61 and get your hands on the Casper Essential for $350-$711.39. Try it for 100 days without risk, and return it if you’re not happy — after that 100 days, there’s also a 10-year warranty.
