Bitcoin is popular now so bitcoin enthusiast do offer that services, one click in google and you will find sites that accept bitcoin for an international flight. I'm not into it yet since my budget would not allow me but like you I am also getting the benefits of paying my bills online with bitcoin.
but usually sold are electronic. we may not be spending bitcoin every day just to buy electronics. maybe I'll be glad when the restaurant or food store that accepts bitcoin as a payment option. of course I'm going to use it every day
But it gets accepted more and more everyday, it's just a matter of time when we can buy other stuff aside from electronics and online services. Just have faith in bitcoins and for sure it'll get somewhere. Also, if it does get mass adopted then for sure prices will go up to unimaginable levels.
