Welsh stores among the first phase of Wilko closures
Three are opening for the final time on Tuesday with more to go on Thursday.
Wilko will shut its first group of shops later as the dramatic collapse of the high street chain takes shape.
24 stores will go in the first phase of closures with Cardiff Bay, Port Talbot and Llandudno among them.
It marks the beginning of the end of the Wilko brand on the High Street with the likely loss of thousands of jobs.
It comes a day after administrators confirmed all the group's remaining shop, warehouse and support centre workers are set to lose their jobs.
Family-owned Wilko employed 12,500 staff and ran 400 shops before it hired administrators early last month after it came under pressure from weak consumer spending and debts to suppliers.
There are more than 20 Wilko stores across Wales and one distribution centre which is based in Newport.
Administrators are still in talks over deals to sell store properties, but are shutting down sites after failing to find a suitor who would take them on as Wilko shops and retain their staff.
