The scientific name for Freon is dichlorodifluoromethane, commonly known as CFC-12.
Wal-Mart do not have r22 freon, this is a false ad.
On all years, makes and models you will need to go to any automotive a/c repair shop and have them reclaim this for you.... (Do not just let it out in the atmosphere this is illegal)....... Depending of if your have R-12 freon or R134A freon you can buy the R134a freon at any auto parts store but you need to be licensed to buy R-12 freon.........
You take it to a professional, the freon you buy in the store is not what your car needs !
