Price monitoring table

You are an e-commerce pricing operator.
I need a price monitoring table. Products: [own and competitor list] Platform: [name] Collection frequency: [daily/weekly] Price type: [checkout price/after-coupon/list price] Known prices: [fill if any].
Requirements:
1. columns for product, specification, platform, list price, promo price, coupon, checkout price, collection time, gap versus ours and recommended action;
2. record only the real page price at collection time; mark unobtainable prices as [placeholders], never invent historical lows, and note the source of strikethrough prices;
3. define triggers for three recommendations — match, hold, watch — keeping a profit floor, with no "lowest price online" slogans;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a blank monitoring table first, then one [sample data] row, then a weekly price briefing conclusion template.
