In my area they are in the Sunday newspaper magazine section, also in the coupons section and AARP publications and just abiout anything I run across. I am not sure what magazines carry them, but you could write to the store web site and ask where you can find them. I had about 8 of them laying around = and took 2 with me before I realized I needed one for each purchase. the clerk was very helpful and rang up 2 sales. One in which I got the 20% off on one set - the other was for 3 and I got the total off the three blades. It would depend on the store and their policies or the cashier.
I mentioned to her that I had never seen another store do such a blitz of coupons and she agreed with me. Between the 2 of us here we have gotten about 8 flashlights. We give them to people we think would like to have one.
In my area there is always more of those coupons every time I open mail.
