I just bought a set of refills, slipped right into my wiper arms for a whopping $4.77 for a set. Around here with the sun and road sand they don't last long so cheap works great. New pair each fall and mid-summer gets me through.

Pair of pliers and 5 minutes... The plastic edged refill blades won't fit intothe grooves in the wiper arms. if you don't have the type of arm that takes the little clipo tp lock it in it is no problem. Just remove the clip and insert the refill blade. it is held in place byt eh ends on the wiper arm itself.
