Don't believe their stock levels. They only respond if you pester them.
I was looking for a bedside alarm clock which had recently been discontinued. I looked around and AVW indicated they had stock remaining. I ordered and paid for Express Shipping (24-48 hours).
It didn't arrive in that time so I contacted them. They responded by saying my order had been raised from "Processing" to "Pending" and later changed it back to "Processing" - no description of what those meant was offered.
After a few more days I checked again and saw the order had disappeared from my account. I emailed them, saying I would start a claim on my credit card if I didn't receive it in 2 days. Only then did they tell me the order was cancelled as they couldn't get stock. They refunded me.

We apologize for being unable to fulfill your order due to the overwhelming demand for this particular product. As we have just come out of the Black Friday season, we did not anticipate such high demand. Like anything in life, products are subject to supply and demand. By the time we addressed all the backorders, we had sold out. Surprisingly, our supplier informed us that we had received all the stock they had. Hopefully, next time will be better.
