Regarding the issue of no shopping cart, specifically on my website; I had a company come out here a few years ago and they gave me their sales pitch about my website.
Gee, really sorry I decided not to tear my website down and rebuild it, it would have cost a fortune and with this hobby taking on water by the day/heading in the wrong direction, not to mention my current webmaster, who has been tremendous the past 10 years or so, told me once that happens, he cannot update the site anymore, so the company that charges you an arm and a leg to rebuild/retool it also from that point on does the updates.
Funny how that works out.
I've been in business full time for over 20 years, have a **** ton of long time, loyal customers, many of whom I chat on the phone/via email with on a regular basis, that's called building relationships, which is pretty hard to do when all you do is point and click.
I've done very, VERY well for myself without having a website with all the latest bells and whistles, I'll be 60 in December and I really don't know how much longer I'll have skin in this game, we'll see how things shake out going forward, I'm well positioned to pack it in basically anytime I choose to, I'm not married to this/forced to keep doing it, I do it at this point because I love doing it, it's a blast and a ball and a **** ton of fun for me, plus the money ain't half bad.
If someone chooses not to buy from me because I don't have a shopping cart and OMG, they have to actually call me or email me, you're probably someone who's all hacked off for the past two months that you can't get a haircut, people around the world are dropping like flies, but God forbid you can't get your millennial brohammer stylish hairdo cut; don't worry, it will all be falling out down the road, one less thing to concern yourself over.
