Deal: Easy and Free $10/$18 Vouchers with STACK Rewards (Gone)

Update: it was fun while it lasted ):

I think there’s a reward-effort ratio to deals, and while $10/$18 isn’t terribly exciting, this is a really low effort way to get free vouchers. Few simple steps:

1. Download Harry’s app (iOS / Android)
2. Enter referral code G41UKS6P
3. Sign up/log in to STACK and add your Harry’s points

Note: while STACK is by OCBC, you do not need to be an OCBC customer for this promo. You don’t need to be a Harry’s customer either

That’s it! You now have 100 Harry’s points to redeem a few different vouchers worth $10, like NTUC Fairprice, Cold Storage and App Store vouchers. If you’re new to STACK, you also get additional 80 Harry’s points which is worth $8 (first 2,500 customers).

STACK offers great deals sometimes

It’s worth noting that STACK has occasional promos where vouchers are greatly discounted. There were $10 NTUC FairPrice and Marks and Spencers vouchers going for 50 points each (or half their usual price), but they are unfortunately out of stock. I’m in two minds whether to just get my $10 Cold Storage vouchers right now, or wait until another promo happens. In any case, free $10 isn’t too shabby.

You can also browse other deals STACK has to offer. I picked up really great deals from it a few months ago and shared it with my Telegram channel. Here’s hoping more sales happen!

Tip: Click View All after each category to view the full range of vouchers available for redemption.

Refer your friends/family

And every good deal becomes sweeter when you can refer your friends and family. You get 50 points, and they get the same 100/180 points. Free vouchers for everyone!
