Right after the 4th of July (for the next day, Thursday) the entire country was out of stock, except for exactly two stores. Now, for Friday (the next day), it looks like a little over half the stores in the country were restocked and are selling again.
It would appear that the demand is really big and is still going strong.
I’ve noticed the same thing. Unfortunately California sells out almost entirely. I’d love to know what their sales figures are.
