If it is automatically canceled shortly after, it's most likely due to the possibility of fraud. Our system screens all orders for this and does a pretty good job, but sometimes it may cancel a good order if you're traveling or have a "suspicious" shipping address. In this case, you may try another card or use PayPal instead.
Minimum Quantity Products
Some products require minimum quantity as specified in the title and description. If these requirements are not met, your order may get canceled. Please ensure you add the minimum quantity to cart to avoid the delay with your order.
