Determine the size of duffel bag you need. They range from helpful "little hand bags" to huge "carry everything and the kitchen sink bags." Think about what you will be placing in them. And if you are going on a trip, it is wise to buy a duffel bag that has some extra room in case you bring back souvenirs.
Decide what kind of duffel bag you'd like to buy. They range from polyester blends, to canvas to leather. Think about how you will be using your bag. If this is more of a fashion accessory, go with high-end leathers and name brand canvases. If it is purely functional and is a bag that will be knocked around, then polyester is the way to go. Also, is it going to potentially get wet where you are traveling. In that case you my consider leather or another material that repels light amounts of rain.
Visit sites like Big Duffels or Luggage for great deals on brand new duffel bags at discount prices. That way you can compare and contrast the different styles with just a single click of a mouse.
Head to second-hand stores, thrift shops and other discount stores. Duffel bags are something people stuff in their attic and then toss into a pile of "donations" on their way to places like Goodwill. But unlike their clothing counterparts, they are usually in really good shape. They may just need a bit of airing out to get rid of that musty smell. If your purpose is more function than fashion, then these are places to get a great deal.
Shop department stores. Target, Wal-Mart, Marshalls, K-Mart and more are all places that carry duffel bags. Simply select the bag you are looking to buy. And keep your receipt, because if you get home and the contents you are looking to carry doesn't fit, then you will want to take it back.
