Relay has everything you could possibly need if you’re about to travel. A huge range of snacks and lollies, cool drinks, chocolates, magazines, newspapers — and my personal favourite, books. On top of that it also sells practical travelling stuff like pillows and earplugs. It really covers everything. While, like all other stores in the airport, the food and drink is VERY pricey, what I found to be a nice surprise were the prices of the books. New titles and a pretty ok range considering the size of the shop, and most books averaging $ 20 or lower. So basically the price you would pay at any regular bookshop. If you’re about to leave Perth and you’ve just realised you’ve forgotten something, chances are you’ll find a replacement at Relay.
