Last day is Wednesday 30 September
Two Sure stores on the Island will close at the end of the month.
The Ramsey and Port Erin shops will shut their doors for good on Wednesday, 30 September.
Sure says it's consolidating business in Strand Street in Douglas, including an online appointment system to cut long queues and free delivery for Island customers.
Sure Isle of Man Chief Executive, Mike Phillips, says "We recognise the importance of supporting the high street and this move allows us to adapt and invest our resources into the Strand Street store and continue to meet our customers needs."
