Planning to buy a mobile phone cost RM2.6k on shopee.

In a dilemma to use either Shop voucher instant RM50 discount OR 6% coin cashback to return 12000 coins (equivalent to RM120), non-stackable...

Taking the 12k coins meaning i have to spend another RM480 in the next 3 months to fully redeem these coins before it expired, which result in more spending..

What is your choice if you in this situation?

Should I wait until tonight and see what is the secret voucher after hitting 1.6mil milestones?
