The access period starts from the date your first friend joins.
The maximum duration of Super Deals access earned at the moment is 300 days. That equals 5 friends being successfully invited.
If you have reached 300 days of Super Deals access then inviting more friends will not extend your Super Deals access or increase cashback limit.
You can invite another friend to prolong your access and increase the cashback limit only once 60 days of access received for the first friend are passed.
If you have a break between accesses to Super Deals, the new access period will start from the date in which your next friend opens his account after the break.
If you have not fully used cashback limit from the previous Super Deals period, it won’t be added to your current cashback limit
