I strongly disagree that websites are a waste of time. I've sold through mine numerous times. In fact, I'm finishing up three hand-painted prints for a couple who saw them at an art festival last August. They recently visited my Facebook photo page, were reminded of the photos, and placed an order. I've also sold to people who had seen my work in a gallery, googled me, and saw work I wasn't showing at the gallery. I arranged for them to see the other work at the gallery, where they made a purchase. They were happy, I was happy, and the gallery was happy (they got their % on the sale).
If you really want to sell your work, in this internet age, you must use it as a marketing component.
