Compare two suppliers

Result: A two-row comparison of paper-bag prices, minimum orders and official sources.
File: suppliers.csv

PRACTICE FACTS
Fictional business: Luntian Supply is exploring plain paper bags. Compare two real suppliers with official public product pages. Record prices in Philippine pesos where listed; keep unavailable prices unknown. This is a small information comparison, not a purchase recommendation. Products may differ in size or specification. Delivery, stock and suitability are not confirmed.

WHAT TO MAKE
- Save up to two distinct supplier/product rows in suppliers.csv using the columns below. Identify the actual product so differences stay visible.
- Record the price per bag only when the listing explicitly states it or clearly gives both pack price and pack quantity. Explain any pack-to-unit calculation in unknowns.
- Record minimum order quantity only when stated; otherwise write unknown. Keep missing prices and product differences visible.
- Include official source URLs and the actual checked date. This comparison does not establish delivered cost or the best supplier.

CSV columns: supplier, product, source_url, unit_price_php, minimum_quantity, checked_date, unknowns

HOW TO WORK
- Ask for a short understanding of the brief and a plan first. Wait for approval before doing the task.
- Write only in this practice folder. Keep the starter brief unchanged.
- Do not invent facts. Label missing information unknown.
- Use official public pages and open the sources; search snippets alone are not evidence.
- If web access is unavailable, stop and ask for official URLs and dated excerpts in sources.txt. Label supplied evidence in unknowns.
- If enough sources cannot be verified, return fewer rows and explain the gap in the chat. Do not fill the file with invented entries.
- Do not contact suppliers, create accounts, add items to carts, place orders or invent quotes.

CHECK THE RESULT
- Open each source and match the exact supplier and product to the row.
- Check price units and minimum quantities yourself. An unsupported unit price or minimum order says unknown; different products are not presented as equivalent.
- The CSV has the seven required columns and up to two distinct options, with dates and gaps visible. No purchase recommendation or delivery promise is implied.
