Our contract with the hotel limits NDK's commercial activity to specific areas around the hotel during the convention. So if you do not have an Artists Alley table, you are not permitted to sell any products at NDK. This includes exchanging money for products and delivering products for which money was exchanged in advance. There are no exceptions to this rule. Performing services for money is similarly prohibited.
You may use this forum to market and even sell your wares, but you must arrange to deliver them at a time and place other than at the hotel during NDK.
