Barely any sales come from favorites on my shop.

I guess this isn’t exactly a question, I just thought it was interesting. So, basically all of my sales seem to be spur of the minute decisions. Most recently, what will happen is a new customer I haven’t seen before will follow my shop, and then immediately after will buy something. I guess this is just surprising to me because the most popular item on my shop is a bit expensive $60-$80). I get favorites at least a few times a day, but I almost never see sales come from those favorites.
