Cant check out

I keep receiving an error message saying: 

Sorry, we can't complete your checkout at this time. Please try changing your item quantity or check your account status.

Please can you assist me in this matter.

You don't say what you are trying to buy or whether the seller is in the UK. This could give some clue, but with luck using the advice given by m25jet  that will solve your problem.

Thank you both for the advice, I'll try the US option. I was buying seeds in the UK from the UK, so the amount was only £6.
