You're obviously targeting people who already like coffee, such as myself: I already buy beans, grind them myself, and manage the process using an Aeropress, and I'm hardly some coffee hipster because I use goddamned Eight O'Clock Columbian Peaks.
Yet, you are trying to sell me instant coffee, which I automatically am wary of because instant coffee is the shittiest coffee you can drink... yet you have no way of convincing me otherwise. Subscriptions are only useful if you can convert the customer, "the first hit is always free."
Also, your entire website is a hastily developed trainwreck: "Copyright $copy; 2017."... Copyright who? The email harvesting call to action in tan needs to follow the rule of thirds to stand out, your contact page needs serious loving (seriously, Google on how to make these), and your front page hero image is goddamned tiny and isn't even full width of the page, and the Sudden/Instant comparison block below it is formatted horridly.
Please hire a web designer, you need someone with experience on how to do this right.
