Using Valora for online payments will depend on the vendor and if they choose to accept Valora as a method of payment.
Alternatively, you can find websites and dapps that accept cryptocurrency as payment. For example, you can purchase gift cards with cUSD or cEUR via Bidali, or spend ETH on Bitrefill. Just use WalletConnect to connect Valora when you checkout.
