Anyone have experience with Happy Mug Coffee? They're more affordable than most online roasters and their shipping is only $3 up to 3 lbs I think. They sell 1 lb and 1/2 lb bags, which is nice. Where the hell did the trend for 12 oz bags come from? What would you recommend for an Aeropress? I think I like medium roasts and am interested in trying coffees with fruity sweet notes that people love.
