The ones we see most often.
REGISTERING A DOMAIN YOU ALREADY OWN
Choosing "register a new domain" instead of "use a domain I already own". The registration fails and the order stalls.
A TYPO IN A DOMAIN NAME
Not reversible. Check character by character before paying.
ORDERING WHILE LOGGED OUT
Creates a second account under a different email, splitting your services. Log in first.
ORDERING A NEW PLAN INSTEAD OF UPGRADING
Creates a second account and a migration you did not need. Use Upgrade/Downgrade.
MISSING THE RENEWAL PRICE
Looking only at the introductory figure. Check the recurring amount in the cart.
FORGETTING THE PROMOTIONAL CODE
It cannot usually be applied afterwards. Enter it before paying.
USING AN EMAIL ADDRESS ON THE DOMAIN BEING HOSTED
When the account is suspended, the notice explaining why cannot reach you.
CHOOSING THE WRONG BILLING CYCLE
Fixable, but tidier to get right at the start.
PAYING BY TRANSFER WHEN URGENT
Manual verification takes time. Use a card if a deadline is close.
