If both of your windshield wipers are the same size you can apply this trick

When you feel like you need new windshield wipers just buy one new one and put it on the driver’s side.

When that one gets worn out, get a new one, put it on the driver’s side, and take the old driver’s side one and put it on the passenger side.

The passenger side one doesn’t need to be as good so your old driver’s side wiper should be fine on the passenger’s side

I look for when my wiper goes on sale and buy one so that I always have an extra one.

Extra tip

Consumer reports says that pretty much every windshield wiper will last about 6 months no matter how good it is. The better ones just do a better job before they get worn out so you don’t have to worry too much about trying to buy high quality to last longer.
