Power of the Crowd: How Shopper Contributions Keep Prices Accurate

Celebrating the community behind BarginBuddy. BarginBuddy isn’t powered by magic. It runs on the collective effort of thousands of shoppers across Trinidad & Tobago who share real shelf prices every single day. If you’ve ever snapped a receipt photo or updated the price of toothpaste in your list, this article is for you.

Where prices come from

Verified online listings – We pull digital catalogues major chains then cross-check with community data.

Shopping-list updates – When you change the price of an item on any list, the new value enters our moderation queue.

Floating “Add Price” button – Every page now has a quick-add FAB in the footer. Tap it, input a price - done.

Verification pipeline

• Automatic sanity checks and flag outliers for standard deviations.
• Moderator review – human volunteers approve, merge or discard suspect entries.
• Source blending – once approved, a price is weighted against existing data based on recency, verification status and source reputation.

How you can help
• Keep receipts and update your price items within 24 hours.
• Use clear photos.
• Add new products if you don’t find a match; our duplicate-finder keeps the database tidy.

Together we turn disconnected receipts into a living market index that empowers households and rewards transparent retailers.
