Delivery can always be an issue if the contractor has many drop offs and you're the last one on the route.
I preferer the Kroger store pickup. If you have their card, all coupons, discounts and cash incentives apply to your pickup order. I like the notice for out of stock and the offer of picking a substitution. At some stores, the double length parking slot makes picking up with your RV doable. I am a bit leery of their shoppers ability to pick the best produce and have clearly had them just grab what was on top of the pile.
Not to mention, the fuel points are tacked on right away so while one is putting away the groceries, the other can be pumping your up to $1 off per gallon in the RV. Heck, saving $35 at the pump is nothing to sneeze at.
