Have any of those $3/1 Purex w/ Zout or Complete Sheets coupons left? If not, check on ebay, The Coupon Master or other online coupon clipping providers to see if they do. CVS is back with another sale beginning March 13th.
Here is the scenario:
Buy one Complete 3-in-1 Sheets @ $3.99
Use $3/1 coupon
Total OOP: $0.99!!
You can also ad match this elsewhere to get the same deal! I did at our local IGA last time and got 6 liquid and 6 3-in-1 Sheets for just under $15 after taxes!
