I saw two brands types, Colombian (Medium Dark roast) and House Blend (Medium roast). The item numbers are #0051137 and #0017367, respectively. Regular price is $36.99 but there is a $2 clipless coupon that expires on August 29.
Compare against last week's Target coffee deal that, for the cheapest units, was $18.98 for 54 K-cups, or $0.3515 per unit (before 5% redcard discount, which makes the per unit $0.33). This BJ's deal works out to be $0.35 per cup.
