The exact part number decides the price: speed, capacity, ECC or registered, and generation all change it. Tested and working with proof (a screenshot or test log) sells above "pulled from a working system". Selling one stick vs. a matched kit or a lot changes the per-piece price. Price per piece and say how many.
