In one sentence, describe what the following article is about:

You'll have a relatively easy time finding typewriters at antique stores, but when purchasing from antique stores, you should be wary of overpricing. Antique store owners are often aware of the value of their vintage typewriters, so they may overprice their typewriters or try to sell you one that's in bad shape. Always ask to use the typewriter before purchasing. While an everyday flea market probably won't have vintage typewriters, antique flea markets often do. Because of the volume and nature of the wares, these one-day sales can be better deals than most other reliable vintage stores. If you're on a budget and don't have a specific typewriter in mind, this could be the place for you! Donation stores like Goodwill and Salvation Army may have old typewriters that have been donated by someone who does not need or want it anymore. While there is a good chance that these typewriters are partially or completely broken, there's also a chance you'll find that perfect, hidden typewriter in the back of the store, just waiting for you. Finding a typewriter at a garage or estate sale can take a lot of patience, but you can usually get a great deal if you do find one. If you're hunting for vintage typewriters in these types of sales, make sure you arrive early! There will probably be others in your area who have the same idea.

Summary:
Shop at antique stores. Find flea markets that specialize in antiques. Check out donation stores. Visit garage and estate sales.
