useful if you're in the area & desperate for a dinner ingredient. Frustrating to pay $1-$2 more for most items & not be able to pay & check-out smoothly. Floor staff very helpful but checkout staff are sometimes in a huddle of 3 in energetic conversation while you're invisible - or like today, they close just as you reach the counter with 2 items, & this after the self-serve option froze when you placed your bag on the indicated section. I'd rather go the distance but options are options.
