#2 and #3 are explicitly points being addressed by jet.com.

Re #2: The entire Jet model is the more you buy the more you save. Taking the baseball example, it's pretty easy to infer when they see you are buying cleats and a glove that they will up-sell you with a bat as well and call out the bundle discount you will receive.

Re #3: The article explicitly discusses that the founder is trying to create an "anti-Amazon" culture that values people and relationships. You can agree or disagree with this approach, but you can;t deny they are actively trying to promote a great culture to work in (no performance reviews, for example).

This is not to say that Jet.com is going to nail it, but you can't dismiss Jet.com's efforts here out of hand either.
