Jet is way better than Amazon for me. So much so that I rarely use Amazon anymore. Prices on Amazon are often worse than local retail stores. I find many products I want to buy are Prime only, Fresh only, or Add-ons. The last two packages I bought took an entire week to leave the warehouse even though they were fulfilled by Amazon. And Amazon has a horrible spam problem. It's difficult to sort out real products from knock-offs sold by a scam seller like SUPER DEAL PRODUCT WORLD or something.

Jet, on the other hand, has no spam problem, prices usually better than local stores, and very reliable free two day shipping. Hopefully they can scale up.
