Instacart said on Monday that it stopped a program that showed different prices for the same grocery item. Some people saw higher prices, while others saw lower prices. This happened even when customers ordered at the same time from the same store. The program was used to study prices in online shopping.

Instacart said the program was random and did not use personal information. Still, many customers felt confused. The company said it wants to be fair and easy to understand. Now, stores will still choose their own prices, but Instacart will not test different prices anymore. The company said clear pricing helps build trust and makes shopping simple. This change starts immediately.
