Credit card question
This might be thick question and a bit waffley but please don't laugh. If you've got a credit card which says 0% for 18 months, does that mean that even if you don't pay it off in full each month then you won't have to pay interest on it, so long as after 18 months it's fully paid?
Whenever I watch the Martin Lewis money things he always says that if you pay it off in full each month then you won't pay interest, so that's what I do with my current credit card, however i'm looking at flights for turkey for next year, and found some good ones with Thomas cook, however I've not got the £800 to pay upfront right now. If I sign up for a 18 month 0% interest card, does that mean i'll be able to take the 18 months to spread the cost and not have to pay any interest.
