A Costco membership costs between $65 to $130. So, it's tempting to wring as much as you can from every Costco run: bulk packages of toilet paper, eggs in 24-packs, 10-pound bags of flour or a 12-pound Japanese Wagyu boneless ribeye roast. Otherwise, you might think, is Costco even worth it if you're still shopping elsewhere?
As enticing as buying everything at Costco might be, it's not always the wisest choice.
