$12 for the small lockers. If you return the key then you receive $5 back. So, then it makes it $7.
I would recommend it for MK, HS, & AK, but at Epcot I wouldn't recommend it if you are going to be in the countries in the evening. It's just too far of a walk to get back to the front of the park to get sweatshirts & then head all the way back to the countries.
HTH!
