Meet entry fees will be invoiced to your account. A small admin fee will be added to each swimmers account to cover coaches passes etc. If a meet requires team travel, you will be emailed to confirm that you wish to be included in the arrangements. The costs will be invoiced to your account after the meet has taken place. Any costs associated with the coaches/team manager's travel will be divided between all swimmers who have taken part in the meet, regardless of whether they travelled with the team or not.
Once you are entered for a meet, there are generally no refunds. One exception is on medical grounds. Some meet operators operate a fine policy where if you do not show for a race you have entered you will be issued with a fine. The fine is often doubled for missing a final. Any fines issued to the club for failure to turn up to a race with no notice will be charged to your account. If you know in advance and certainly before withdrawals close on the day you may usually withdraw with no fine being issued.
