I made small purchases with cryptocurrencies, but none of them were physical products. It can be useful for purchasing services, but we don't have much use in the real world yet, we can only buy things in a few countries or in a few stores.
I have not made such a shopping choice yet, not had such an opportunity
In a world where crypto is not totally accepted as a currency, i find it more useful to simply use it as an investment rather than to use it in purchasing goods and services. Though some physical stores are accepting crypto, but most are still accepting fiat only. So if i have enough fiat to spend, then i don't prefer to spend my crypto instead. Besides, crypto is more profitable if you keep it as an investment, that is why i prefer not to spend it as much as i can. I have not made such a shopping choice yet, not had such an opportunity
