What our customers are saying:

"I could not believe how quick the shipping was to Australia and the price, well it was so cheap that I didn't believe it would arrive so quickly. I bought something else from another city in Australia which took longer to arrive than the one from Pegasus in the USA. Well Done Pegasus Racing!"
