Just because we can, doesn't mean that we should. I never flood with my product, I hold it in store and release it in a set amount each day as things sell in order to try to retain a high value for my labour (similar to the way the real world diamond trade works). Flooding is unnecessary, and a serious pain in the butt! If you aren't sitting on an absurd amount of product, you won't need to clear it out at rock-bottom prices, you'll spend less time crafting to try to turn a profit, and your labour will be worth more.
