Some credit card companies do not permit card holders to make international transactions without prior approval. If your credit card is being declined, please try contacting your credit card company and ask them to make sure transactions with VetShopMax (based in Australia) will not be blocked. 

Alternatively, in the checkout process, select the “pay by Paypal” option. You don’t need to be a Paypal member and paypal processes payments from Visa, Mastercard, Discover Card and American Express.
