It's a bit confusing.
According to this:
http://www.48months.ie/boiler-plate/add-on-rules
Add-ons are valid for one calendar month from the date of purchase.
...
There is no carryover of any unused add on allowances.
But actually add-ons can last more than their "normal" monthly validity period depending on when you buy the subsequent membership. Maybe I'm a bit thick but I've never fully understood the exact rules. You can try if you like:

Hope this helps.
