Disappointed Aldi and Lidl customers claim they have been unable to find key products featured in high-profile ad campaigns this Christmas.

Dozens of Aldi customers took to social media to question the availability of Christmas favourites including serrano hams, mince pies and turkey.

“I have been to my local branch five times now and have not found any mince pies,” one customer posted on Aldi’s Facebook page.

Another posted: “Very unhappy about the lack of serrano hams in stores. I have visited five without success despite the heavy marketing of this product in the national press.”

Lidl has also had its Christmas availability questioned by customers on its Facebook page.

Both Aldi and Lidl had advertised products as limited.

Aldi was unable to provide comment before The Grocer went to press.

A Lidl spokeswoman said: “We have accurately planned our stock volumes to avoid disappointment. It can be very store dependent as to which lines will sell quicker than others. However we have increased volumes this year on our key Christmas lines to ensure availability.”
