One of the grounds to close a question as off-topic reads:
Questions on price-shopping for specific goods or services are off-topic as prices and availability change frequently in many locations. See: What is a shopping question?
How does it apply to How to Buy Schladerer Kirschwasser in Frankfurt, Germany? (three votes to close as of writing this)?
The justification mentions price and availability. The question might not strictly speaking be a price-shopping question but availability can also change quickly and the question is unlikely to have long-term value to anyone.
We might want to amend the text to broaden the scope of the rule a bit.
Quite clearly, the rule does not apply. It's not a price-shopping question and can be interesting to other travellers seeking this local delicacy as information of this sort typically remains valid for many years.
Rule-creep is not a good thing and if the point was to forbid all shopping-related questions, that particular justification would not be formulated in that way. Furthermore, older discussions confirm that discouraging questions about the best price for something that's widely available (as opposed to tracking down hard-to-find products) was really the concern here.
We might want to remove the word “availability” to make that even clearer.
