I love https://www.luigicases.com - it's the web site for an Italian gentleman who makes leather cases and straps for Leica cameras. But the web design is straight out of the 90's, along with loads of extraneous text and even some family photos. And you can't actually buy anything via the website - you send the guy an email and a corresponding Paypal payment (https://www.luigicases.com/a000-PURCHASE-info.htm).
If the goods are handmade then the bad UX serves as a rate-limiter to constrain demand to supply. I'm assuming the system works well for him as otherwise he'd switch to a better solution.
If you'd ever done A/B testing before you probably would not make this statement. Also, it's quite possible they prefer to stay small and don't want more business.
Basically, it's so bad, it's charmingly good.
