Bob's primary focus is arcade parts. He doesn't take credit cards or PayPal, and he is not a spring chicken.
He almost retired in 2001 or so much to the great dismay of this community.
Web design is very low on his list of priorities - to put it into perspective think of the following:
1) Foremost - if the web page causes us all to stop buying, Bob will simply retire again. That is not a good thing for any of us.
2) Bob is the only guy I know who still does business like my dad did all his life - trust and respect. He respects his customer base, and provides free advice - he never sold me anything I didn't need even if I asked him to (if I ask for the wrong part, he'll correct me and sell me the right one - sometimes he has LOST a sale because he would rather me not make mistakes than sell me an unneeded part). Trust - he sends all my stuff before he ever receives my check - because I always pay immediately and never sent a rubber check - so since I'm here in LA as well, everything comes to me overnight.
3) His cap kits come with a printed sheet and map when appropriate. That's not required - he could just tell you where to find a PDF and make you print them yourself.
4) Lagniappe (extras) - those little candies and calendars. Good business sense and not required at all.
Yep, the site was designed 13 years ago (by another collector here in LA, strictly as a favor to Bob in appreciation for his services) in Notepad and hosted for some time on a crappy computer set up as a web server on a T1 line and then eventually moved but never redesigned.
If you have complaints and can do better, and have time, then offer to redesign it for him - he can't do it himself.
I would rather continue to get the service he provides than have him waste his time learning how to spiff up his site.
