The latest from Westside Financial's Graham Green
If you've still got any old £10 notes you need to now take action. You only have until Thursday 1 March to spend them before they're officially withdrawn by the Bank of England.
Here's what's happening and what you can do if you miss the deadline.
Last year the government brought out new £10 notes to try and combat counterfeit notes in circulation. Following the launch of the new polymer tenner in September, the older £10 notes featuring Charles Darwin have been gradually phased out and will cease to be legal tender in a few days' time.
It's believed that more than a quarter of the old £10 notes, worth a staggering £2.2 billion; remain in circulation - so if you've any old tenners, the last day to use them is Thursday 1 March. After this date, retailers will no longer accept them. So spend them or put them in the bank this week.
