We've changed how our system handles instances where an expired auction order was cancelled. If a user accidentally forgets to pay his expired auction order, our system will check to see if this is the first time he has forgotten to pay. If so, an email warning will be appended to the Order CANCELLED email.
If the same user does not pay for his second expired auction order, our system will ban him from participating in future expired auctions.
If submitting payment on time is an issue, please consider setting your Dynadot account's autopay settings to use account credit and fund your account appropriately. This way, you can ensure your expired auction orders will always be paid in full (assuming you have enough account credit).
If you have any questions, please let us know.
