There are multiple ways to save a nice percentage of the price of a new wooden rocking chair.
One thing you could do is buy an unfinished wood rocking chair. These items typically can save you half the cost -- because you are buying a wooden rocking chair that is unfinished, thereby saving on the materials and labor of a finished chair.
Unfinished furniture stores exist in many locales, if you want to shop offline. There may well be one near you. (Just be certain you have the time and wherewithal to finish your new chair yourself.)
While shopping out there in the place where other people dwell, be sure to check out a Cracker Barrel restaurant and general store if there is one near you. As you may know, those folks are always happy to sell you a new wooden rocking chair. Catch them on a sale day and you'll be golden!
Also, you can sometimes find the treasure of a gently used wooden rocking chair at your local neighborhood Goodwill Thrift Store, if you are patient and not "married to" one particular style of rocking chair.
As you shop, I hope you find a wooden rocking chair that pops and helps you smile about your home decor.
