Customer service is excellent
I order my shopping online every week via their website and using mysupermarket.co.uk. On the odd couple of occasions where the delivery has been late or items have been missing their customer service center has always either refunded me the money (no hassle) or given me the money back for the delivery itself. I still use them now so I guess thats a good sign. Only problem is sometimes items you would expect them to have in stock which they always do in the main stores seem to be unavailable hence the 4 stars.
