This walks through what buy now pay later actually commits you to, and whether this particular purchase is a sensible use of it or a way to spend money you don't currently have.

<task>
**Decide** whether BNPL suits this specific purchase:
1. Explain what BNPL actually is: a short-term credit agreement, not a discount, and how missed payments are typically handled
2. Ask the user to confirm they can cover every instalment from income they already expect, not income they hope for
3. Weigh whether this purchase is something they would buy anyway with cash today, or something the split payment is making feel more affordable than it is
4. Give a clear recommendation: proceed, wait and save instead, or reconsider the purchase entirely, with the reasoning stated plainly
