Are you sure its 6%? I order 1st day and the 1st day promo (23-Jan - 1 day offer only) for Shopback was 5%. After the 1st day, the rebate is set to 3%.
As I know, the 6% is for aircond, TV, fridge, etc.
Go in Shopback, search for Samsung and look at the rebate % base on category.
This is the current rebate at Shopback today. It maybe different on 1st Feb previously.

Edit: Looks like yours is 1.8% as per Mobile phone category. You should have went for Shopback plus, get additional RM30 bucks. 1st month is free, after that is RM4 a month. But you can cancel it after that. You also can get enjoy the perks they offer.
Well its still not a lost, you still get the rebate, just lesser. And remember to setup your bank details later so that you can wire back to your desired bank. But the cash rebate may take a while to get it on Shopback.
you got a point, issue is, i forgot to capture the detail of shopback but i do remember that is for the S25 promo.. I only captured the below. ANy way to trace back what was offered on that day, 2nd feb 0000 to 0200 HRS?
