BEWARE of incorrect register pricing, and store policy of NO GUARANTEE OF ACCURACY. Only my vigilance prevented a $4.50 overcharge for 3 bottles on featured Heinz ketchup on a Tuesday. Phone call of complaint to Mars headquarters received comment that this was an isolated incident, because they had received no other complaints. MY RESPONSE was that other customers were merely unaware that MARS had, in effect, STOLEN from them by inaccurate computer pricing on final day of featured sale price. Also, manager had to be called to register to void the incorrect price, but I received NO APOLOGY from either the manager or the cashier for the delay needed to correct the price.

They are our supermarket of preference. Their produce section is outstanding, as is their deli and fresh meat. Overall we find their pricing better and their staff very helpful.
