How pricing actually moves in supplement brands

Supplement pricing is a three-front war: brand subscription pricing (e.g. AG1's $79 sub vs $99 list), Amazon's Buy Box rotation, and unauthorized Amazon resellers undercutting MAP. A buyer needs all three signals.

What this looks like in week one
A growth lead at a $20M supplement brand sees a competitor drop their subscription price from $69 to $55 on a Tuesday. By Friday, they've matched the price and built three landing pages targeting the competitor's branded search terms. The competitor's first-touch conversion drops 23% the next month.

Questions buyers in this category ask.

Can you track Amazon Buy Box price changes?
Yes. Track the Amazon product URL, the scanner reads the current Buy Box price (which changes every few hours as Amazon rotates between sellers) and alerts you when it crosses your threshold.
How do I track subscription vs. one-time pricing on brand.com?
Most supplement brand pages show both prices. The scanner detects pricing tiers (subscribe-and-save discount, multi-pack discount) and lets you pick which to track. Brands typically track competitor sub price as the leading indicator.
What about unauthorized Amazon resellers undercutting MAP?
Track each Amazon listing separately. When an unauthorized seller wins the Buy Box at $20 below MAP, you see it within the hour and can file the violation with Amazon Brand Registry the same day.
