The Square Enix Store (the same store where you can buy FFXIV itself and it's expansions, it is not the same thing as the 'FFXIV Online Store' which sells in game content for the game), sell the time cards. For EU, that's here (default for me is the specific Australian store as shown in that URL but scroll to the bottom left of the page and change the country to your region and it should change the page accordingly).
