It depends on the store. At Menards, definitely! Usually their specials are large items & trying to grab boxes to hold everything is difficult.
At WM, I try to. I work with my SIL & one of us is with the cart at all times. We leave coats in the car, purses at home & only bring a water bottle, cell phones & charge cards. The cards are much easier than trying to juggle cash. We don't take the paper with us, but we do transfer our shopping list to a small notebook (like a restaurant order form) to keep track of the impulse items, as well as our "needs".
So much better than shopping alone!!!
