Paypal sometimes changes that setting back to using DCC and some websites directly debit your Paypal account without showing any Paypal pages which means DCC without notification. The Visa and Mastercard terms of use state that a shop using DCC must ask you if you wish to use DCC or not for every transaction, and this is hardly satisfied by having a hard to find checkbox which sometimes automatically reverts back to using DCC. Just request a chargeback if you don't have the option to disable DCC.
