Lidl's are selling 6 packs of lucozade energy in varies flavours for only £1.99. They were also selling their veg half price but I know this might be a regional offer and is on regularily.
They had potatoes at 49p, butternut squash 49p etc.
My local branch were also selling threee large boxes of reduced items( bedspread covers, cat scratchers, kitchen equipment etc ) - that were previous specials. This was the Lanark store but might be worth popping in to your local branches to see if they have a similar offer .
