John and Ray, good information - thanks!
I have a 2016 MACs catalogue which shows the seat cover set I need as $469. Then the 2017 Fall catalogue at $505. Now the online price of $585, a 25% increase over 2016!
So something is going on there and I need to look closer to the source, as Ray suggested.
I had not thought about the foam being done locally so that helps. The auto upholstery guy is only 2 miles down the road.
