What I can't understand with you, is why anyone who is interested in becoming your customer, must gives you his money for a product that you don't have it and you don't even have the courtesy to mention it on your site. How difficult is to write OUT OF STOCK or SOLD OUT or PENDING, EXPECTED. If you don’t know to do it, see this

So simple. A serius site that respects its customers will not take future money their clients and will certainly inform them -as you saw- on the product you have or have not.
I think you have created a very negative opinions. Any major site in Earth wouldn't do what you do.
I am very sorry that whenever i need to buy a product from you, I waste my time to do such discussions like these, that we do now.
