After a discussion with @mnmkng a decision has been made that we want our courses to use the https://warehouse-theme-metal.myshopify.com/ sample shop by Shopify, because it's a sweet spot between

• Stable but sterile learning environment
• Unstable but real-world learning environment

The sample shop uses most of the technologies we need for demonsration of scraping techniques useful in the real world scenarios, but won't change from week to week. Also we do not have to maintain it.

Possible risk is that the template disappears or gets replaced one day, and we'll have to rework our courses, but the risk is low and can be easily mitigated.

As per this decision we should phase out https://demo-webstore.apify.org/ as our own demo website.
