With bitrefill alone you can buy everything you need on a daily basis, from food, clothes, gasoline, household appliances, etc.
With shopinbit you can even buy cars.

What I see here are prices quoted in fiat that presumably will be converted to Bitcoin on checkout at the ever wildly fluctuating exchange rate. So prices in Bitcoin effectively fluctuate wildly. How can you plan financially? Like do you set aside a bitcoin budget for food each month and expect it to last?
