# OfferPrecheck - llms.txt > LLM-readable manifest. Features-only; no fabricated traffic claims. ## Entity - Product of: LX AI Micro-SaaS Factory - Product site: https://offerprecheck.lxsaihub.com/ - Hub: https://lxsaihub.com/tools/offerprecheck.html ## Positioning - Product name: OfferPrecheck - One-line: Pre-check pasted promo copy against the published deceptive-pricing guides (16 CFR Part 233) and the deception standard (16 CFR Part 251); get a scored, severity-ranked pre-check report with discount arithmetic against your parsed price pair in 60 seconds. - Honesty: Heuristic pre-check — not a pricing-law certification or legal advice. No historical-price verification, store or ad-account connection, or platform-policy measurement performed. Whether a "was" price or stock claim is true depends on your own records; challenge outcomes depend on regulators, marketplaces and ad platforms. ## Checks - Reference-price patterns — "was", "regularly", "compare at", "list price" vocabulary with the reference price extracted from your text (16 CFR 233.1 former prices; 233.2 comparisons) - Discount arithmetic — parses money tokens (US thousands-comma and EU decimal-comma formats), pairs reference and sale price, recomputes the real % off, and flags claims that overstate it beyond a ±2-point rounding tolerance; an unparseable pair is skipped and reported, never guessed - "Free" offer conditions — "free with purchase" / BOGO patterns whose purchase conditions or cost disclosures are missing (16 CFR 233.3) - Scarcity and urgency asserted as fact — "only 3 left", "today only", "closing down", ranked by how categorical the claim is phrased - Material-terms advisories — absolute promises and quantified claims escalated by offer type and market; EU/UK/AU consumer-law reminders labelled ADVISORY; the tool never verifies price history or connects to stores, marketplaces or ad accounts ## Policy references (snapshot 2026-10-22, re-verified reachable from this build) - Guide Against Deceptive Pricing (16 CFR Part 233): https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-233 - Former prices (§233.1): https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-233/section-233.1 - Comparisons and fictitious discounts (§233.2): https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-233/section-233.2 - "Free" is good if you really mean it (§233.3): https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-233/section-233.3 - Deception policy (16 CFR Part 251): https://www.ecfr.gov/current/title-16/chapter-I/subchapter-C/part-251 - RFC 2119 keyword conventions (normative-language style): https://www.rfc-editor.org/rfc/rfc2119 - Note: ftc.gov returned 403, EUR-Lex 202, gov.uk 404 and shopify.com 000 from this build's network; those hosts are excluded until re-verified (see lib/rules/SOURCES.md). EU/UK/AU positions are advisories only. ## FAQ Q1. What is OfferPrecheck? A1. A micro SaaS for pre-publish offer checks: paste the exact promo copy, get quoted findings by severity, a 0-100 deceptive-pricing risk score, discount arithmetic from your own price pair, and a fix checklist before you hit publish. Q2. Will a high score make my offer legally compliant? A2. No. Exposure also depends on whether your reference prices were actually offered, whether stock claims are true, and on reviewer discretion the scan cannot see. It is a heads-up, not a pricing-law certification. Q3. Does it verify my price history or connect to my store? A3. No — deliberately not. It checks only the text you paste; substantiation appears as an ADVISORY reminder to verify in your own records. No store, marketplace or ad-account connection, no price scraping. Q4. Price? A4.
