Frequently asked questions

Can Price2Spy monitor supplement-specific channels like iHerb or Vitamin Shoppe?

Price2Spy can be configured to monitor many websites, but its monitoring is URL-based rather than channel-native. MarginSonar is pre-configured for 11 supplement-relevant retail channels with extraction logic tuned to each retailer's page structure.

Does MarginSonar offer repricing like Price2Spy?

No. MarginSonar provides competitive monitoring and intelligence, not automated repricing. If repricing automation is a core requirement, Price2Spy or a dedicated repricing tool may be a better fit.

How do the free trials compare?

Price2Spy offers a self-serve free trial. MarginSonar offers a request-based 14-day preview for qualified supplement brands, with the workspace pre-seeded with competitor data and history before the clock starts.
