Costco grocery pricing is hard to beat, but the stores do not offer a good shopping experience due to  overcrowding.  In addition, at my local Costco  there's a total lack of available parking spaces between the hours of 1:00 pm and 3:00 pm, Monday through Friday, and public transit or a bicycle are wholly inadequate for trips to Costco.   Very much looking forward to online  grocery ordering and delivery.
