Step-by-Step Guide to Comparing Discounts

Step 1: Locate Your Product

Use the search or filter function within the spreadsheet to find the exact product you're interested in. Ensure you match the model number for accuracy.

Step 2: Analyze Seller Columns

Look across the row for your product. Compare the prices and promotional notes for each listed seller. Pay special attention to terms like "limited-time offer," "subscription discount," or "free shipping."

Step 3: Study the Price History Graph

This is the most powerful feature. The price trend line will show you:

• If the current price is near a historical low or high.
• Typical discount cycles (e.g., drops every 6-8 weeks).
• Seasonal patterns (e.g., major sales during Black Friday, Amazon Prime Day, or holiday seasons).

Step 4: Factor in Additional Costs

The lowest listed price isn't always the best deal. Use the notes in the spreadsheet to account for shipping costs, tax differences, and warranty services offered by different sellers. A slightly higher price with free shipping might be cheaper overall than a discounted price with high shipping fees.

Strategies for Planning Purchases at the Right Time

Identify the "Buy Zone"

By examining historical data, you can determine a "buy zone"—a price point at or below which the product is a good buy. Set alerts or check the spreadsheet regularly when the price enters this zone.

Anticipate Seasonal Promotions

The spreadsheet will reveal annual trends. Plan your major purchases around predictable mega-sales events that the data confirms. If you see a price starting to drop in anticipation of an event, you might wait for the event itself for the deepest discount.

Avoid Post-Promotion Price Hikes

Sometimes prices rise immediately after a big sale ends. The historical data helps you recognize if a "current" price is actually inflated compared to the regular average, preventing a poor purchase timing.
