We was there in August and they had a lot of drinks, water and things in the cold cooler. (Including Milk) Then they had a section with chips and snacks. We was able to get a small container with crackers and canned tuna (We was tehre during the huricane and it was what food we could find that day) We also bought a box of cereal. they were very limited in selections.
There was a lot of miscanellous Disney stuff too. I saw kids toys, things to buy like pins and lighted toys, Tshirts and other clothing items. It was not a great selection but at least enough to look into getting a few items cheaper (And remmeber no tax ever) They had color books I thin and things of that nature. I personally didnt by any souveneers there but I looked a bit.
They had other sundry items like baby diapers, a small amounts of medicines and suntan lotions.
Pretty much think 7-11 in Orlando. (I say orlando because I noticed all the stores down ther have some souvineers in their stores)
Thats pretty much the type of things you find there. Maybe a little bit more souveners than 7-11 but pretty much similar stuff otherwise.
