 Meantime, the perks of shopping at Costco, they will cost you more. The mega retailer is raising its membership fee for the first time in seven years. Starting September 1st, the basic membership fee will increase $5 to $65 a year, and the premium membership will jump up to $130 from $120 annually. But those hot dogs will still cost $1.50. They're the best deal. I love Costco. The price is protected.
