Im not gonna buy anything using bitcoin. Just hold it for long term is good for me because i know that the value will increase like past years.
Other than holding, i am using bitcoin for buying tokens in ICO.
As far as i know AMAZON an online company that sells almost anything accept bitcoin as a payment. You can almost buy everything using bitcoin in a 100+ companies worlwide that accept bitcoin as a payment. This is why I love bitcoin because it is easy to use specially in online payment transaction.
