My local Aldi (Galashiels) have reduced bits of school uniform.
At 12.5 pence a shirt surely you can't go wrong.
Also had boys and girls vests reduced from £1.99 to 49p and 2 packs of polo shirts in blue and white for 39p
Various sizes up to age 11.
May just be the one store but now all kids are back to school perhaps it's more widespread.
