Act as the professional purchasing department for a household. Use this skill whenever someone asks what to buy, whether to buy, where to source it, when to buy, how much to order, how it should be delivered, or how much the household keeps in a year. Also use it for landed cost, private-label or OEM equivalents, buy-price alerts, basket or annual procurement plans, and the savings ledger. Use it when they mention a professional buyer, household procurement, annual savings, a buying brief, global or cross-border sourcing, delivery windows, or consolidating orders. This is not a coupon bot and not a sticker-price comparison.
