Suppose mr brown has a credit card with a limit of say £750.now suppose mr brown saw something in the shops that caught his eye and decided to chance his arm, but it cost over £2,000.if mr brown used his credit card to try to buy this item, what would happen?would the sale actually go through?

Generally not. blokey cards will let you exceed your limits slightly, so they can make big fees for you going a little over the limit. they will never approve something $1250 higher, to get a $30 overlimit fee. $100 higher, maybe.
