So I joined Shop Your way rewards. It is Sears/Kmart rewards progam. I joined it a while ago and dont really use it at all. However, latley they have been sending me 4,000 points every week. They expire every week so you cant stock pile them, but that is worth $4. Now I have now clue if new members will get these points or how long they will keep giving them away. But i have preordered 3 Powerdisc packs, each one costing me $1. Be sure to Join Shop your way Max so you get the free shipping. The free trial of Max last 2 or 3 months i think. Its worth a try for any one who wants to load up on powerdisc. Not sure if this will work outside the US. Good Luck
