I went to the Harrogate Small Animal show for the last 3 years. I discovered Dust Free Hay there and have ordered it over their website ever since. There also tends to be small stalls full of things for guinea pigs not seen in shops. Although this year there were fewer of these stalls. But they included Piggiepigpigs who makes bedding for pigs and rats,customised sweatshirts with guinea pig logos, water bottles (a type specially for GPs who tend to play with the type normally sold in shops, there was one stall that had a good selection of guinea pig huts and syringes and I bought some stuff to put on paws to stop bleeding. There was a lot there of interest to buy that you wouldn't always see in shops. You could get a lot of this stuff over the internet but I find it better to actually see things before buying. I spent quite a lot this year as I am now more aware of what my pigs need. There was a Burgess Stand and a team from an Agricultural College giving advice which I found useful. If you went with children it's a good introduction to small animals. But the downside is the showing of the animals.
