I really never use curbside pickup. We go to BJs vary rarely (maybe once a quarter) so maybe use curbside for one or two of those trips. I've only used curbside p/u for the grocery store I don't usually shop at because they offered me $40 off $75 to try it. It took way longer than just going to store. I didn't purchase any meat or produce.
Honestly DH and I like grocery shopping together. I use lots of coupons (digital, in store only etc.) and there are also unadvertised sales or managers specials. I also want to pick out my own meats. So in store it is. The in-store part really doesn't take that long. Planning out the trips takes longer since I go to at least 2 stores.
