The Math Behind Ice Cream and Boba Loyalty Points

I broke down every redemption option at Soft Swerve and HeyTea point-by-point to find the best bang per loyalty point — turns out the flashiest rewards are almost always the worst value.

I wanted the optimal redemption strategy for loyalty points at two spots I hit constantly — Soft Swerve (ice cream) and HeyTea (boba/tea) — instead of blindly saving up for the big-ticket rewards. So I priced out every option by the only metric that matters: dollars saved per point.

How I valued each reward

The math is just value of the reward ÷ points it costs = $/point. Higher is better. Prices I used:

  • Soft Swerve: $7.50 for a 1-scoop cup, $2 per topping, $2 waffle-cone upgrade, $12.50 per pint.
  • HeyTea: $8 average per drink.

The headline finding: the cheapest, most boring reward (a few dollars off) almost always wins, and the aspirational rewards you'd save months for are the worst per-point deals.

Cup/cone + 1 topping120$9.50$0.079
Two pints500$25.00$0.050
Sundae cup200??

$5 off dominates everything by 25%+. The "two pints" reward — the one that feels like the jackpot — is the worst confirmed option at half the value of just taking $5 off.

HeyTea

Free single drink1500$8.00$0.0053
15% off – 1 drink ($8)300$1.20$0.0040

Solo, take $1 off — it's the highest $/point you can reliably hit. Ordering for a group flips the answer to 15% off.

The "free drink" (1500 pts) is strictly worse than "buy 1 get 1 free" (1000 pts): same $8 of value, but 500 extra points. Never save for it.

The 15%-off breakeven

15% off only beats $1 off once the discount is worth more than ~$3, i.e. 15% × order > $3.00order > $20. Below that, the flat $1 off wins; above it, the percentage scales with your group:

  • 1 drink ($8): saves $1.20 → $0.004/pt (worst)
  • 2 drinks ($16): saves $2.40 → $0.008/pt (ties BOGO and 50%-off-2nd)
  • 3+ drinks ($24+): saves $3.60–$5.00 → $0.012–$0.017/pt (best)

It caps at $5 of savings on a $33.33 order, so there's no benefit to a single giant order beyond that.

Caveats

  • All HeyTea math assumes $8/drink — pricier specialty drinks push the 15%-off breakeven lower.
  • Soft Swerve's sundae cup (200 pts) is unranked: no pricing available. It'd only compete if priced above ~$20, which is unlikely.
  • 15% off needs 3+ drinks ($24+) to beat $1 off — if you rarely order for a group, just take $1 off.
  • BOGO (1000 pts) and 50%-off-2nd-cup (500 pts) are equal per point, but the 500-pt option accumulates twice as fast.
