As you are now doing so well and posting that profits are up...isn't it about time you considered the customer! START SUPPLYING BIODEGRADABLE OR PAPER BAGS!
You must have seen the hundreds of complaints about service. Long long time ago it was amazing... tissue and items were packed for you. Now they are nearly thrown at you - even after spending hundreds of pounds - and you have to carry them off. ALL good shops now packing with paper or biodegradable bags.
COME ON M & S MAKE AN EFFORT...
