Personally, I love drop shipping because then I don't have to do the fulfillment or manage the inventory myself. These days, though, I actually prefer getting my shirts screen printed on demand (not digital printing), and then drop shipped out to my customers. That way I don't have to invest in an inventory up front. Of course my margin is smaller, but it's worth it for me because I don't have to deal with the hassle and headache of inventory stuff.
