There are a handful of questions where the OP wants a cheap, or the cheapest option. There are cases where you cannot really give them a good answer because they claim that every option is above their budget.
In some cases the constraints that they put on make it impossible to answer the question, or at least give a good answer.
Should these kind of questions be closed or put on hold until the budget constraint can be removed, or modified to the point where the question can have a definite answer?
Here are a few examples of questions like this:
They would like to soundproof their door for under $20. The best answer would be to replace the door with one that is solid core. Obviously, that is way above their budget.
The question here is very vague, and they are looking for a free fix to some problem that they are not even describing very well.
What is the cheapest way to stiffen a tube/pipe?
Here is another example where it is very difficult to give a good answer.
What is the cheapest/easiest way to make bookshelves?
Questions like the ones above seem like a waste of time, especially because the answers are not getting very many upvotes.
