Take home a 125-ounce bottle of Cascade Advanced Power Gel Dishwasher Detergent for just $7.49 at Costco. It’s already priced low at $9.49, but apply this month’s Costco instant savings and save $2.00.

Compare this cost to the Amazon price of $18.99 for the same size bottle! That’s a whopping $0.15 per ounce versus the Costco price of $0.06 per ounce. While the Amazon deal includes free shipping, I’m all for shopping locally at my Costco and saving $11.50.

Walmart has a 75-ounce bottle on rollback for $5.97. The price per ounce is $0.08. While the price is fairly comparable, Costco wins with the lowest price again.
