I wish the original owner all the best. They had a good idea, and if the model worked, others will pick up the good ideas and discard the practices that didn't. Any storefront has a cost that can make or break the business. After 39 years, it's time for a change if they started in their mid-20s. I'm sure the owner (s) have taped up enough boxes that they never want to see another roll of packing tape again.

If they did close the storefront front there is always a possibility of prices going down.
Employees, liability insurance, any type of health and welfare package, Social Security, Workman's Comp, shipping cost, rent or taxes on the property (if you own it), utilities, maintenance cost, advertisement, Internet storefront, web page management, blog maintenance, banking and CC cost, the list goes on, it's expensive to run a store front when you add up the total cost and a living wage for employees. BTW someone gets to mow the lawn, clean the windows, and unplug the toilets too.
I was always surprised at their return policy and how easy it was to use. I know I had to return items 4 times over a 25-30 year period. Excellent customer service. I always cracked up when you would read about a customer buying a sub, blowing it up by cranking it, and then leaving a nasty comment about how PE had ripped them off. It's never hard to spot abuse.
In any case, whoever took the business over, I wish them well, and hopefully another long run of affordable parts for the DIY and repair community.
