Instacart shoppers are using the app's 'reorder items' button to see how much grocery prices increased over the years

• E-receipts from apps like Instacart give a highly personal view of the effects of inflation.
• Shoppers using "reorder items" on years-old orders can see exactly how much prices have increased.
• In some cases, baskets have seen price hikes exceed the overall official rate of inflation.

Paper receipts are fast becoming a relic of a bygone era at the grocery store, especially as app-based ordering and tracking have become more popular.
