The Post Office is another place where you can take your old round pounds after this date.
Ritu Vohora investment director at M&G said: "While many shops are saying they will continue to accept the round £1 coin after 15 October lots of people have already started to check their piggy banks and glove compartments so they can spend or bank their round pounds". Speaking to the Express & Star, he said: "We will still be accepting them as long as the bank takes them from us".
Aldi said: "We've been ready to accept the new £1 coins since they first came into circulation in March".
The old pound coin will officially lose its legal tender status as of midnight Sunday 15 October 2017, meaning it won't be accepted anywhere in the UK.
However, there has been confusion over the withdrawal of the coins, with some shops pledging to continue accepting the pounds coins after the October 15 deadline.
And a trade association representing small shops has advised its members to continue accepting the round coins to provide a "useful community service" to customers.
Around 1.2 billion old round coins have been withdrawn from circulation but about 500 million are remaining with less than a week to go. After that time, businesses can stop accepting it and will not automatically be giving it as change for notes.
The reason behind the new coins is that they will be harder to forge as one in 30 of the old round ones were thought to be fake.
The coin also has a new design on its tail side, created by 15-year-old David Pearce, who won a competition organised by the Treasury.
Royal Mint are now encouraging all old pound coin owners to spend, bank or donate their coins before the deadline.
Charity box collectors and those who save loose change have been urged to go through their coins and sort out the old from the new to make sure that they do not miss out.
The firm will allow customers to pay with the old-style coins for a week after the October 15 deadline imposed by the Royal Mint.
So even then you Tesco shoppers only have until October 22nd to use up your old tender.
RBS/NatWest also said it would encourage customers to try to hand in their old coins as soon as possible.
