Story time! When Jet.com launched they had some promos going on so I wanted to check out what it was all about and ordered a bunch of stuff. I think at that point they had 2 day shipping over 25 without a membership. Their signature purple package arrives on time, in a larger than expected box. I open it, and there's a smaller Amazon box inside. I open THAT and it has all my items. I got two receipts, one from jet.co…
I figure that some people have identified arbitrage opportunities in pricing differences between the two sites and are making easy money receiving orders on one site and fulfilling from the other.
