Original Summary

Comparing prices online is pretty straightforward. Comparing prices at stores around you is a lot more annoying. You usually know what you paid, but not what the same item cost a few blocks away. I’m building a receipt-based price comparison tool, and it raises an interesting product problem: the information people want depends on other people already contributing it. Receipts seem like a useful starting point because they show what someone actually paid. But there’s a lot to account for before you can tell someone they could have gotten a better deal. Was it the same package size? Was the cheaper price a promotion? Did it require a loyalty card? How old is the receipt? And would driving to another store wipe out the savings anyway? A receipt can prove a purchase happened. It can’t prove that price is still available. That makes me think the early version needs to be useful even without much community data. Tracking someone’s own price history could be a starting point, with local comparisons becoming useful as coverage improves. For founders who’ve built products that depend on user contributions, how did you make the product worth using before the network was large enough?   submitted by   /u/AdEfficient8374 [link]   [comments]
