I've never had a credit card. Tbh I don't really understand how they work. I don't want to spend money I don't have. However I often buy things online and sometimes it's a pain having to pay for stuff on my debit card and then if I need to return it, I have to wait for refunds to be processed etc. If I had a credit card to use for ordering online, does that mean I can potentially order an item, and then return it if need be, before my monthly payment is due - therefore not having to pay out and wait for refunds?
Also if a credit card says "0% interest for X months", does that mean if I use it but pay the full balance each month, I don't pay anything at all extra on top?
I've heard about cash back credit cards... what are they and how do they work?
I've been on money supermarket and used the eligibility checker thing and it came out as being eligible for several, with Sainsbury's showing as something like 2yrs 0%.
I don't know whether having a cc would be useful or if there's no point seeing as I've managed without one all my life so far!
