It depends on which country's website you shop in. When shopping on American shopping websites, the default currency is USD and the price is USD. You can pay directly with ABC credit card, and this ABC credit card must be a dual-currency credit card, which supports US dollar payment. When shopping on other countries' websites, pay attention to the currency marked with the price. If it is not dollars, then choose dollars to pay first.

It should be noted that there is a currency conversion fee of 1.5% for consumption abroad, which means that 100 USD is spent abroad, and 1.0 1.5 USD should be paid back when repayment is made.

When you use a dual-currency credit card in consumption abroad, you can conduct transactions through different channels, such as UnionPay, Visa, MasterCard, American Express, JCB, etc. When the UnionPay channel is selected, all foreign currency transactions will be converted into RMB amount according to the real-time exchange rate and credited to the RMB account of the international card. The repayment method is the same as general RMB consumption. Moreover, UnionPay does not charge any handling fee, which can save the currency conversion fee. When you choose Visa and other channels for credit card consumption, it will be automatically converted into US dollar arrears. Whether repayment can be made in RMB depends on the specific issuing bank.
