Shopback has upsized their Cashback for amaysim to $35 for certain plans, was a maximum of $25 earlier.
They also seem to have revised Cashback for certain other plans. For Eg; Since Unlimited 55GB (new plan this month) is only costing $15 as a promotion, the Cashback is only $7.00 instead of the usual $25.
The full list of updated Cashback as per the plans is as below:
Unlimited 60GB/120GB Mobile Plan & 20GB/50GB/90GB/100GB/150GB/240GB Data Plan
$35.00
2GB/5GB Data Plan & Unlimited 5GB/30GB Mobile Plan
$21.00
Long Expiry Unlimited 125GB
$17.00
7GB Data Plan
$10.00
Unlimited 55GB
$7.00
Unlimited 1GB/8GB and Pay As You Go Mobile Plan
$3.50
The 5GB plan is $20 and $21 cashback?
$1 profit if that is correct.
From shopback rates: "2GB/5GB Data Plan & Unlimited 5GB/30GB Mobile Plan $21 "
Which is a bit strange because there is no 2GB or 5GB data plans that I can see
EDIT:
Looks like its on Cash Rewards too
