Shopping plan
A skincare shopping plan for a fixed budget

Your shopping task
Plan a cleanser and a moisturizer purchase inside a spending amount you set, using your own prices and the replacement interval you actually expect.
- Step 1: Set a spending amount before comparing package sizes.
- Step 2: Start with what you already own and record the replacement interval you actually expect.
- Step 3: Use the unit-price tool to compare a current purchase.
- Step 4: Use the replacement-cost tool to estimate annualized spending from your own replacement interval.
- Step 5: Keep the upfront cash total separate from the annualized total.
