Rick Bowmer/AP Costco's total sales in recent fiscal years exceed $64 billion. Selling everything from toilet paper to cars, the discount warehouse has made a name for itself thanks to its bargains. However, not every Costco deal is worth your money. Award a superlative for "Best Deals," and most people will nominate Costco. A one-stop shop for nearly everything imaginable, its total sales in recent fiscal years have exceeded $64 billion. There's no denying its success and popularity, but bigger isn't always better.
