When we were out and about at Rite Aid, I noticed they had quite a few Physician Formula products on clearance, the "Special Value" marked Mineral Wear products were on Clearance for $2.73, and I used $3 peelies from the New Mineral Wear display to get those FREE! They were only marked on clearance at one store I went to, but if you price check, they should ring up at the Clearance price.
***"Special Value" Mineral wear comes in the loose powder (like one pictured above) and also a pressed powder. Oh, and they come in a separate display, not on the wall where all the other Physicians Formula makeup is, although I did find a couple misplaced on the wall with the $13 ones. Just make sure you get the ones in the blue box with the pink square on the top right hand corner labeled "Special Value".
