Anyway the point here is that you can pretty much buy anything with bitcoin. Slowly there is more and more mainstream companies offering bitcoin as payment like apple, wholefoods, and many more. What about you? What is the most bizzare (or totally normal) thing you purchased with bitcoin?
Buying something with Bitcoin is normal, you can buy anything with Bitcoin if you have and if they accept Bitcoin in any platform you are buying something from.
The main problem is the Bitcoin restriction in some countries; if your country is not accepting Bitcoin as method of payment generally, you will have problem if you are a store owner because your country might sanction you for using Bitcoin publicly even after the restrictions.
Nevertheless, you can accept Bitcoin or pay for something with Bitcoin if you can and if you are familiar with Bitcoin transactions and if you feel it will be safe for you; but in my opinion, I think since Bitcoin is an asset, holding for long will be better than using it buy something.
