Why 8.99 Never Looks Dangerous

Small repeat costs hide because your brain sees one payment, not twelve months.

A small monthly number is easy to ignore because your brain sees today, not the next twelve months. Repeat payments exploit that blind spot: each one feels harmless while the calendar quietly does the multiplication.

The fix is not “never buy anything”. Multiply repeat spending by 12 before deciding whether it is still tiny. If you still like the trade, keep it without guilt. If the annual number makes you laugh nervously, you found a leak.
