Apart from the ridiculous p&p costs ML is very useful for us....and to be fair it does work well most of the time. However, the lockdown has shown them to be lacking. If I buy items I expect them to be delivered within the stated timeframe given for the item. Especially as the lockdown had been operating for well over a week before I purchased the first item.
I kind of feel sorry for the sellers. I get the impression they have to do what ML tell them.
