One of the options you're presented with when nominating a question for closure on the basis of being off-topic is as follows:

> 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?](http://meta.travel.stackexchange.com/questions/241/what-is-a-shopping-question)

The "What is a shopping question?" link links to https://stackoverflow.blog/2010/11/qa-is-hard-lets-go-shopping/ which is basically arguing that so-called shopping questions should be off topic because they're primarily opinion basis (which is already a reason for closure).

Anyway, I'm willing to accept that asking around for the "best price" is off topic but asking about the availability? There are lots of questions on TSE that ask about where to find things that aren't closed. eg.

- http://travel.stackexchange.com/q/84656/4868
- http://travel.stackexchange.com/q/84529/4868
- http://travel.stackexchange.com/q/84210/4868
- http://travel.stackexchange.com/q/83502/4868
- http://travel.stackexchange.com/q/84210/4868

etc.

The question that is specifically prompting my own is http://travel.stackexchange.com/q/78840/4868
