At this point the guy who jacked up the price of 60 year old AIDS medicatio has Scumbag of the Year sewn up pretty tight.
I love Costco, but there’s definitely a learning curve. There’s also more of a price advantage if you buy some stuff organic regularly. Our staple purchases are 1.5 gallons of organic milk, organic eggs when needed, 2 loaf packs of organic bread, and paper towels/toilet paper as needed. When the little guy was in diapers costco couldn’t be beat on Diapers/wipes.
Stuff like razors and shampoo I’d skip. Clothes are very hit or miss. Same with seasonal items. Meat really takes careful planning, although it’s not too hard to buy a 3 pack of organic chicken and use one right away and freeze the other two.
Before I had a baby costco was much less of a weekly destination. There’s definitely a trick to when to shop. Midday on a Saturday will leave anyone hating life. We used to live across from the one in Mission Valley, which actually made it our go-to Gas station. It was great to zip over 30 minutes before close and get cheap gas with no line.
