One indication of how the economy is doing is to look at how fast vendors fill orders to be delivered. If orders are being filled quickly, it means they are not busy, i.e., business is bad.
In the second quarter of this year, a survey of Orange County businesses found the percentage saying goods are being delivered at a faster rate than usual was much larger than those who thought deliveries were slower than usual. The upshot? As deliveries get filled faster, the market gets glutted and prices go down.
