Buy: Luggage
Even though there is not a huge luggage selection at Costco, it does offer good but affordable suitcases. Clark Deals even included Costco as one of the best places to go if you want luggage bargains. According to the website, you should also look out for coupons if you want to save even more money.
Skip: Name-brand clothing
Have you ever seen those designer clothes at your local Costco? Be warned that they are going to have lower quality compared to the items you will see at the original store. Many manufacturers like to cut corners when it comes to their Costco products. Feel free to buy the items if you like them, but it is not reasonable to expect them to be of good quality. Marshalls offers better bargains on name-brand items.
