well I did my monthly shop at asda tonight and went prepared, the till girl was laughing her head off at the varied carrier bags I had...
the freezer stuff went in thick o2, topman & matalan bags
I had morrisons, co-op & various clothes stores... she almost cheered when I pulled out an old asda one
In fact I didn't use any of their bags on offer at all and they were still handing out the free ones, the 5p ones do look very sturdy and only have asda in really small writing in the middle, but didn't need any of those either
