No, as Section 75 only applies to items bought on certain types of credit. But there is a way you can access some purchase protection using a prepaid card. Prepaid cards allow you to load them with cash before spending. They don't credit-check, so they're useful for people who can't get credit.
For example, Cashplus offers a contactless debit 'account' that behaves like a prepaid credit card, offering purchase protection similar to Section 75 – although this is NOT legal protection.
