BEWARE, add at least 6% to the price you see when using Sports Direct's Australian website. Despite clicking through to the Sports Direct Australian website, seeing all of the product prices in Australian dollars, and paying with an Australian credit or debit card, you will be charged a foreign transaction fee by your bank of at least 3% (because sportsdirect.com is based in the UK) and because Sports Direct will use dynamic currency exchange converting our dollars into their pounds, and then back into dollars with our bank, leading to another hit of at least 3%.
BEWARE, the price you are quoted online will never be the price you are charged.
