I went to CoinEx at the weekend, if buying something see what price the seller will go down to and then say that it is too high. Go back towards the end of the show and haggle slightly more, often works lol
Make sure you know what you are buying and watch out for pickpockets, there were quite a few at CoinEx!!
There will often be two or more of the same coins at different stalls so see which one will give you the better deal.
Finally, always look through the 'bargain bins' I always find cheap and rare coins in them!!
That's all for now.
Good luck!

P.S. Enjoy yourself!!!
