The steak weighed less than we ordered: settling a shared grocery order with Gemma
This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built My friend and I share Walmart grocery orders. In September my friend sent me 13 product links, I added 8 things of my own, and the order went on my card. When it arrived, we had to settle up from the receipt. It was more fiddly than it should have been: The sirloin steak is sold by weight. I ordered it…
This story details a shared grocery order between a friend and the author, which was settled using a custom tool called splitcart. The author ordered a sirloin steak for $13.45, but it only weighed $11.79. Three items were on rollback and therefore cheaper than listed prices. One taxed item, Tide detergent, was purchased by the author's friend.
The total order cost $130.94, and after accounting for the steak's correct weight, Rollback prices, tax, and a $5 tip split evenly, the friend owed the author $94.27. To simplify splitting future orders, the author created splitcart. The tool takes the group chat discussing the order, the receipt (or a screenshot of it), and calculates each person's share.
The author demonstrated how to use splitcart by running it on their own September order, with Gemma, an AI model, confirming that all the calculations were correct.
