We bought a fridge and a dishwasher on consecutive days. The salesman for the fridge didn't listen to questions or answers, didn't know about his products and came across as cocky.
That sales lady for the dishwasher was the polar opposite! Very professional and listened to us.
I suggest that they arrange regular staff appraisals to weed out the sub standard ones.
Price wise they are quite fair. One other thing to consider is the "free delivery". When we asked for it we were told that we would have to pay an extra £20. The salesman told me that "hey, I don't own the company, I only work here. It is what it is" nice attitude eh!
