Another bargain source for outdoor furniture is consignment stores, particularly the ones that specialize in furniture. If there's one in your area, get in touch with the owners and let them know you are looking for outdoor furniture. They may have a policy or habit of calling potential buyers when sought after items come into the store.
Another way to find bargains is to wait for end of season sales. Many of the larger local outdoor furniture specialists have end of season sales that can significantly save you money. Additionally, check out the big box home improvement stores; they often clear out their remaining stock at low prices, and they'll usually sell their display models at a steep discount. If you can wait until fall, you can save quite a bit of cash!
Plastic outdoor furniture, which you can find at discount department stores and home improvement stores, is a popular pick because it's economical and durable. As a bonus, if you can't find patio furniture in a color that matches your décor, you can simply paint it with a spray paint made specifically to bond to plastic. Plastic furniture can also be dressed up with inexpensive cushions, tablecloths, and umbrellas to make it look more festive and substantial, and it's far cheaper than other types of outdoor furniture.
When searching out your bargains, remember to sit on the furniture before you buy. If it seems rickety or unstable, or just doesn't feel comfortable, don't buy it. Bargain furniture that isn't safe or comfy isn't a bargain at all.
