Luggage sets can be prohibitively expensive. And if you don't travel frequently, spending that kind of cash on something that mostly sits in a closet doesn't make sense. Luckily, there are many sources of discounted luggage. If you want the latest, most ergonomic wheeled suitcase, you won't save that much no matter where you look. But if you're not obsessed with brands or willing to carry your bags the old-fashioned way, you'll find plenty of cheap, functional suitcases and duffles in all sizes.
Head to you local Goodwill or thrift store. Many people donate their old fixed or wheeled luggage sets to these stores, which then sell them for dirt cheap prices. Most thrift shops won't accept luggage sets unless they are in good condition. Make sure to clean any luggage before you use it, though.
Visit the pawn shops in your area. Expandable luggage and rolling luggage are commonly pawned items. Almost all pawn shops will have some sort of luggage for sale. This is also a great place to find cheap designer luggage. Remember to always haggle with the owner; never settle for the asking price.
Buy your luggage online. Check out LuggageBase.com, which is one of the best sites for clearance luggage. There are quite a few online luggage vendors — the most important consideration beyond the level of discount is shipping costs, which can be considerable for big pieces or hard-shell luggage. Don't just look at luggage-specific sites: General vendors like Amazon and the online shops for discount stores like Walmart and Target also sell luggage sets and sometimes discount or waive shipping fees.
