I was at my local target yesterday (Dallas,TX) and saw Filtrete 3M Ultra
Pure 1500 Air Filters for $4.32. They weren't on clearance or anything,
just hanging out with the air filters. I bought 6 of them (all the store
had).
Very YMMV (Target). Here's a link to what I bought:

Good Luck! If people ask, I'll post my receipt when I get home.
