A few years back, my local mom Facebook group started a weekly thread to share the best deals on groceries around town. We tried to look through supermarkets’ circulars to pull out the best deals we saw. Someone started a spreadsheet comparing prices at Costco versus non-warehouse stores.
The effort fizzled quickly. Why? Not because it wasn’t useful, but because it was so much work to do on a volunteer basis.
What if a local news organization did this for us, making it part of a reporter’s job? Better yet, what if local news organizations around the country made it part of their mission to help readers compare grocery prices around town? What if, on every digital local news site, a “groceries” vertical highlighted the week’s best deals across stores? Where I live, Market Basket generally has the lowest prices on everything — but once in awhile Star Market beats its price on butter or broccoli or bagels. A weekly digest letting me know this would provide a genuine service. A regularly updated Costco or BJs spreadsheet on a local news site? Yes, please.
Probably more of a !selfhosted@lemmy.world response, but have a look at Heisse Preise?
