HeyMax vs. ShopBack: Why I Always Check Both (And Why Cash is Making a Comeback)

If you have been following The Shutterwhale, you know I am a huge advocate for optimising every dollar spent. For a long time, the introduction of HeyMax felt like a game-changer, offering Max Miles that unlocked arbitrage opportunities (specifically with the World of Hyatt programme) that simple cashback couldn't match. However, the landscape changes quickly. Recently, I have found myself using ShopBack more frequently than before. This leads to the golden rule of online shopping: Never be blindly loyal to one platform.

To make an informed decision, you need a baseline valuation. Without it, you are comparing apples to oranges. My strategy hinges on converting Max Miles into World of Hyatt points. While airline miles typically float around a 1.5 to 1.8 cents valuation, I value World of Hyatt points significantly higher at approximately 3 SG cents per point. This is because Hyatt’s fixed award chart allows for incredible redemptions at luxury properties like Park Hyatt and selected Andaz properties, where cash rates are often sky-high.

While HeyMax offers a steady stream of miles, ShopBack frequently runs aggressive campaigns with boosted cashback rates. Even if you are a die-hard miles chaser, you must do the maths. Cash is king unless the expected value of points exceeds the cashback.

Let's look at a real-world example I encountered recently while booking airport transfers on Trip.com. I opened both apps to compare:

• HeyMax: 2 Max Miles per dollar

• ShopBack: 6% Cashback

With my 2 SG cent per Max Mile valuation, shopping through HeyMax implied a 6% return which matches ShopBack’s 6% cashback exactly. When the value is equal (or even marginally close), Cash is king. Cashback is liquid and it does not expire - it also does not suffer from devaluation, and most importantly, it does not have conversion thresholds. With HeyMax, I need to accumulate a minimum of 10,000 Max Miles before I can transfer them to World of Hyatt. If I only earn 200 Max Miles from a transaction, those miles are stuck until I earn 9,800 more. The 6% cashback from ShopBack, however, is money in my pocket that I can use for anything - including buying points directly if I truly wanted to.

I have developed a simple habit: I take 10 seconds to open both apps before every transaction. Here is the matrix I use to decide:

Scenario	ShopBack (Cash)	Heymax (Miles)	My Choice
Standard	1% Cashback	1 Max Mile (3% Value)	Heymax (Miles value exceeds cash significantly)
Upsized Cash	10% Cashback	1.5 Max Miles (4.5% Value)	ShopBack (Cash value is undeniably higher)
The "Tie"	6% Cashback	2 Max Miles (6% Value)	ShopBack (Equal value = Cash wins for liquidity)

It is easy to get comfortable with one app and default to it for everything. I fell into that trap with HeyMax for a while because I loved watching my Max Miles balance grow towards that next Hyatt redemption. However, as the Trip.com example shows, ignoring the competition means leaving money on the table. ShopBack has been fighting hard for market share recently, and as consumers, we should take advantage of that - especially when the sub-category cashback is higher. Keep your point valuation in mind (whether it is 3 cents or lower for you), but always treat cash as the superior currency when the numbers are close.
