That s not an easy one to answer.Do you have an existing website and want to add a store or are you starting from scratch? if so would recommend storebuilder. You need a way of securely taking payments etc.It makes a big difference.Starting from scratch I would recommend Paypal at the other URL below.
Not sure what kind of store you re looking for, but I ve found Zazzle and it s great for merchandise. You have to use their stuff, but you can upload your own designs.
