Guinness Draught Stout At Costco - 24 - 14.9 Oz Cans for $28.99 YMMV (Membership Required)
The Costco stores in Bradenton and Brandon, FL had Guinness Cans as of yesterday, 5/9. I always look for Guinness in Costco and rarely find it. While I suspect this is Costco's regular price it is much less than other stores charge, like the $7.99/4 pack that Total Wine charges in my area. I don't know if this is regional or nationwide, but is about the lowest I have ever seen for Guinness 14.9 oz cans.
