As Blue Apron (APRN) sinks to $8, eMarketer provides one reason to keep an eye on the stock. According to numbers from January, Blue Apron had the largest subscription base by far for box brands. https://twitter.com/eMarketer/status/877216764450537472!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");The company still needs to tweak the model to figure out the profitability equation, but a large base of users provides hope for anybody buying the stock at these levels. Dollar Shave Club sold to Unilever (UL) for $1 billion last year and the company focused on subscriptions that only cost a few dollars a month. Blue Apron collects $57 per order, but the market only values the stock at $1.6 billion now. Anybody think $8 is the low?Disclosure: No position
