Yes… however, buyers can fund the payment by credit card but through PayPal, as opposed to funding from their bank account or from funds in PayPal. Sometimes buyers aren’t aware that PayPal protection applies irrespective of the funding source.

OP, as you used your card directly, you’re protected by your bank/card issuer only to the extent of your card’s T&Cs. That means the timeframe for disputes is as stated in your card policy details. It differs not only from bank to bank, but also from specific card to specific card. The shortest I’ve seen is one month, and the longest was 6 months.
