You'll often hear that buying groceries at the supermarket is more economical than purchasing prepared meals. Such is the case right now with frozen organic strawberries sold at Costco, Trader Joe's, and Aldi, among other stores. The great thing about shopping at grocery stores that pride themselves on solid customer service is that in situations like this, you don't have to worry about losing money.
My family generally shops at Costco on a weekly basis, and when it's my turn to pick up groceries, I often take a "get in, get out quickly" kind of attitude. It's not that I don't love Costco, but rather, I tend to be pressed for time during the workweek, so I try my best to limit the minutes I spend in the store.
Many people join Costco to get access to bulk household essentials and grocery items. Costco actually carries a wide range of apparel for men, women, and children. Costco even carries footwear, accessories like gloves and hats, and some specialty clothing items, like party dresses.
