Initially, your Flexi eGift Card will have a very long validity period, typically 3 years (although in some cases your particular eGift Card might have validity as short as 6 months). Check the expiry date shown on the main Flexi eGift Card page.
When you choose an eGift Card or Voucher, it will have a shorter expiry date,
typically within 3 - 6 months, and sometimes as short as 1 month. What this means is that the expiry date of your Flexi eGift Card can change depending on the selections you make.
As an example, after selecting this iTunes eGift Card shown below, you would have 6 months to activate it before it expired, not the original 3 years of the Flexi eGift Card. For this reason it is very important to pay attention to the expiry and validity periods shown.
