We went on Sunday. I bought the 3 for $12 online. I am not sure if you can buy at the park. Most items were in the $4-5 range. We did get a cheese sampler in Italy that was $12. I was surprised they let us use it! Also meat crepes in France were $6.99.
The only downside to BG's version of food and wine is that they did not anticipate the demand for wine and slushie beverages. They were out of a lot of stuff.
