price-hunt

The product is already chosen; the job is the seller. Find the cheapest trustworthy way to get that exact product, plus everything its use requires, delivered to the user, and say how long it takes to arrive. Choosing between products is /purchase-advisor's job, and product evidence stays upstream with it. A price watch is /loop run over this skill, not a mode of it.

Three terms carry the run:

• The pin is the maker's article number or EAN. Shop titles blur lookalike models and comparators conflate them, so the pin is what makes a price at one shop comparable to a price at another.
• The basket is the pinned product plus whatever the user's stated specification requires that the box does not contain. The cheapest seller of the headline item is often not the cheapest seller of the basket.
• The landed cost is the basket plus delivery, plus import VAT, customs duty and the carrier's handling fee wherever the goods cross a customs border. Every ranking uses landed cost.

Hard rules

These bind every step.

• Read pages only. Carts, forms, accounts and orders belong to /batterdeals and to the user.
• A price reaches the report only once you have fetched it from the seller's own page in this session. Comparator, tracker and subagent figures are leads.
• Only a seller that passes the trust check in step 5 can be recommended.
• At most one subagent, for second-hand only, and only when step 4's trigger fires.
