Yes, Moroccan Tan definitely did last year (free sachet samples and half price trial size bottles). I'm not too sure about the other brands. Even if they aren't giving out free samples, if they do trial size bottles (200-250ml sizes) I'm sure it'll be cheaper to buy there at the show. They usually have bulk-buy deals on, so if you're thinking of stocking up, I'd consider taking a small wheeled suitcase or similar to carry them in! Although Crazy Angel held on to mine until we were ready to leave, it was still handy transporting them from the show out to the car.
