Pepsi products were on sale, 2 liters for $1.00 and then I got the 15% off, so each 2 liter was only $0.85. That is like at least $0.20 cheaper than the commissary...I know...I just checked!
They had a sale on Right Guard deodorant, 2/$5. I got the two, downloaded two coupons for a total of 2.50 off, then got the military discount, so I only ended up paying $ 0.87 EACH. They are normally $3.50 each at Walmart!!
