Aldi shopper find mysterious $20 charge on her receipt

An Aussie mum has been left befuddled by an unexplainable $20 charge on the receipt for her weekly shop at Aldi.

The woman found the charge labelled ‘groceries’ which tacked on 10 per cent, $20.60, to her total shop and bringing the cost up to $269.25.

She took to a mother’s group on social media to see if anyone could explain the odd charge while adding that she had also been charged for GST as well.

Members of the group and former Aldi employees theorised the extra cost could have been a mistake by the cashier.

Others said the mum’s unlucky payment was a warning for other to keep their receipts so they can receive refunds on mistaken charges.

One member claiming to be a Aldi store manager said the checkout employee had ‘incorrectly pressed’ a button and added on the 10 per cent.

A former employee revealed the supermarket’s checkout machines have ‘a small button on our register that says 0 per cent GST and another 10 per cent GST’.

‘These buttons are hardly used but can be mistakenly pushed during scanning or punching in codes for produce,’ they said, according to Yahoo.

‘Take the receipt back to the shop and they will refund.’

Another said the extra cost could have been manually entered by the cashier for an item without a barcode such as meat or a Special Buy item.

Daily Mail Australia has contacted Aldi for comment.

The mother’s experience has rekindled warnings from experts to always request a receipt when shopping and to review the bill before leaving the store.   

Christine Seib, editor-in-chief at Canstar Blue, told the publication that Aussie shoppers should save their receipts or consider using self-serve checkouts.

She said self-serve checkouts allowed customers to ‘see and assess the cost of each item’ before it’s bagged.

For those who don’t want to carry around physical receipts, Ms Seib said a number of stores can email a bill of sale while banks and rewards programs now store ‘smart receipts’ to be accessed later..
