I normally start out showing pieces on DPW. If they sell, I'm happy. If they don't sell, I will then often put them on hold and put them in other venues (local gallery, competitions, etc. When that happens, I have to frame them which is an additional expense (and often a big one). So, I increase the price. If it's going into a competition and I have to pay a fee, I increase the price to cover the fee. If I have to ship it framed to get to the competition, I increase the price to cover the cost. I also increase the fee to cover all those costs (which haven't gone away), when I remove it from hold and put it back in my active DPW inventory. If it sells at one of the other venues at the higher price, I update the price for my records and mark it sold on DPW.
