Where is your supporting evidence for your "fact"?? You make the claim, you provide proof of said claim. "It doesn't sell well and is often not in stock"..... Half of that statement has the potential to be contrary to the other half. If it's "often not in stock", then either yields are very poor, demand is simply outpacing supply or merchants simply aren't stocking the product. This is where supporting information becomes vital. Do we know, for a fact, what the actual demand is for the product? Do we know, for a fact, what the product supply actually looks like? Do we know, for a fact, what the retailer sales figures are? Either provide the relevant data, or accept that you're wrong. As you're the one making the claim, burden of proof is on you. Why should anyone else have to research supporting evidence for what YOU claim as fact?
