Costco sells a 70 ounce box of Kellogg’s Frosted Mini-Wheats for $8.49, or $0.121 per ounce.
Safeway sells a 24 ounce box of Frosted Mini-Wheats for a new low price of $4.49, or $0.187 per ounce. Wow! So, Costco is saving me $4.62 per box, compared to the Safeway per ounce price.
If I consume 2×70 ounce boxes per month, my annual savings is $110.88.
