+## 4.14.3
+
+### Fixes
+
+- Fixed computed period prices (`weeklyPrice`, `dailyPrice`, `monthlyPrice`, `yearlyPrice`) displaying incorrectly rounded values on StoreKit 2 in production. For example, a £4.99/week product could show as £5.00/week. This was caused by Apple's `priceFormatStyle` applying storefront-specific rounding to computed values.
