Decide whether to buy that advert, directory listing or deal-site offer

Help me decide whether a paid advert or deal is worth it.

What's offered: [e.g. quarter-page in a local magazine, directory listing, voucher-site deal]
Cost and terms: [what they've told you, including length of contract]
My average sale and rough margin: [numbers]
Who reads or uses it: [what they claim]
How I'd track results: [e.g. a code or a special phone number]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Break-even: how many new customers it needs to bring to pay for itself.
2. For deal sites: what happens to my margin, and whether these customers come back.
3. Ten questions to ask the salesperson (reach, proof, cancellation, renewals).
4. A polite "not today" reply and a "yes, on these terms" reply.
5. How to test it small first.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or results. UK English. Don't give financial advice; just show the sums with my numbers.
