Pending (pre-authorization) charges are a way for the processing bank to confirm your account has a positive balance. This is useful in the services industry for example where tips are processed separately. Pending charges can be for an amount between 20% and 130% the order total, so they may not match the order total. They will disappear in 1-3 business days.
If your card payments are not going through at all but you are seeing these pending charges, it typically means your billing address does not match the one you entered on checkout or your bank is blocking the transaction. Please call your bank to confirm the billing details and make sure they are not blocking the transaction. If it still doesn’t go through please contact us.
