for now I have never bought a product that can make payments using bitcoin, in my country bitcoin is still not widely used for payment transactions.
Same with me, I have not tried using bitcoin to pay or purchase anything. I cannot find a store in my place that accept bitcoin as payment. Bitcoin here is not very popular maybe because some people do not understand cryptocurrency well. It is sometimes misunderstood as a scam and ponzi. But I nkow somehow bitcoin will become a global currency.
