Linking Your Folksy Shop to Facebook

Hi, I am new to Folksy and have been working on stocking my shop. I have a facebook page and have also stocked my facebook shop with the same products then when the person goes to pay they are diverted to my Folksy shop. The difficulty is that once diverted they aren’t diverted directed to the product and then have to start the whole process again by finding item and then buying. It also means updating the facebook shop and Folksy shop simultaneously- is this just extra work? Face book do give the option of checking out through them rather than diverting to Folksy. What’s your thoughts? Is there any advantage in linking it to folksy?
