Start with the exact identifier
Match the retailer SKU and manufacturer model whenever possible. A shared product name is not enough: pack counts, generations, colors and included accessories can change the price dramatically.
Confirm the store—not just the chain
Terminal clearance and manager markdowns can be store-specific. Record the store number and location. Treat a report from another state as discovery evidence, not local availability.
Check when the observation was made
A timestamp matters because limited clearance can disappear quickly. Newer evidence deserves more weight; an undated screenshot deserves less.
Separate shelf price from checkout result
A shelf tag, app result, scanner price and completed checkout are different evidence types. Note exactly which one was observed instead of combining them into a vague claim.
Never treat inventory as a promise
Retail inventory systems can lag, damaged goods may remain counted, and another shopper may already have the item. Call the store when appropriate and avoid asking employees to hold suspected pricing errors or ultra-limited clearance.
