Divine intervention will help. Sacrifice a few Humes to the Gardening God (Matthew Broderick) on Watersday, and swallow three widowed frogs on the Ides of June.
I see only one person has enough balls to raise the price, and their patience paid off - he made over 1/2 a mil on these in one day. If everyone else keeps underselling, eventually they will be worthless. Stop lowering the selling price of these. You are only hurting yourself. They are a high demand item, and sell very fast.
