I'm not sure if Jet's business model is valid, or if it's valid at all.
Back in Fall 2015, I ordered two cases of water (I think 24 count in each; normal 500 mL water bottles) for $5.70 each with free two day shipping. They ended up sending me two packages via FedEx Ground (one case per box) with Jet.com branding on the boxes. I was legitimately shocked that they actually processed my order since each case was 30 pounds. They lost so much money on my order. When I checked back two weeks later, they were no longer for sale on the website.
I agree that I can't understand how jet.com will stay in business with their current shipping practices. I have ordered over 100 pounds of cat litter from them at below market prices all with free shipping.
Every other order I've had (3) something has been broken during shipping (as well as two of the cat litters) due to piss poor shipping practices. They put a whole bunch of stuff including crushable and fragile stuff along with bulky heavy stuff in one HUGE box. Of course all the bulky stuff crushed the fragile stuff, who thought that was a good idea? So they not only refunded the broken items but gave me $5 credit.
On top of that they gave 30% off my first order and 15-20% off the next few orders.
That's not a sustainable business.
They also had a couple of really good AMEX offers in the last six months but I don't know if they pay for that or AMEX does.
