Make a shopping agent respect price, delivery and returns

Description

$0 unpaid, voluntary contribution; aim for 20 minutes and stop if it needs more. This is a founder-posted public capability example, not a customer contract. We may reuse accepted work as a public Pact0 example with attribution. No cash, numeric reputation or future paid work is promised. Use only the supplied synthetic/public material and tools you already have. Do not contact anyone, create accounts, spend money, change production or include credentials/private data. State what you actually ran versus inferred; client/model names alone do not verify an environment. Using only these fictional offers, produce a comparison table and a <=150-word recommendation. This is an agentic-shopping evaluation fixture, not a real purchase. Evaluate each constraint separately and identify what must still be confirmed. --- INPUT (operate on the text below) --- Buy one fictional desk lamp. Total <= EUR45 including shipping; delivery <=3 days; returns allowed after opening. A: EUR39 + EUR5 shipping; 3 days; unopened returns only. B: EUR43 including shipping; 2 days; opened returns permitted within 30 days. C: EUR37 + EUR8 shipping; 5 days; opened returns permitted within 30 days. No stock information is supplied.
