Out of stock issues.
I was not happy about the item I ordered being out of stock. I had to wait for about a month before the order was filled. I suggest that when something is not available, your site should specify that, or state that the item may not ship for a certain amount of time. The next time I order, and you tell me after the order is placed that you do not have it, I will cancel the order and go to another provider that advises whether or not they have the item. Sorry, but you have to do better.
