Why did my product show in stock on the product page, and not in stock when I check out?

While the inventory showing is real time, a few things can affect actual stock levels; orders are allocated on a first placed basis, your order will only be processed when you submit the cart, if another order was placed before then, the stock will get allocated to the other order. Occasionally we will have discrepancies in our inventory levels, if this occurs a customer service representative will contact you to discuss the options, we will do our utmost to meet your request in the timeframe you need.
