it's not big news to anyone here how most of us feel about subs.
but lately, i've been getting a couple of bucks, here and there.
for a while it was mostly subs.

i am wondering if these "bigger" sales are from the same buyers who bought my subs? do you think so?
what is your thought on this from your own experience?

fotographer is right, hali. It's not that your subs are escalating into sales, it's just that as  your downloads increase, your work is checked out more. Therefore, buyers are beginning to notice , and in turn, it results in them selecting your images. All the better for you
