J.M. Smucker shrinkflation: how to spot it on your next trip
Shrinkflation is when a brand reduces package size while keeping the shelf price the same. J.M. Smucker sells across jam, peanut butter, coffee and more - here is what to watch.
Why J.M. Smucker shows up in shrinkflation conversations
J.M. Smucker is a major presence in the grocery aisle. Like every large packaged-goods company, it has used multiple levers to absorb input cost pressure: occasional price increases on a line, format changes (more single-serve packs, fewer multipacks), and quietly reduced package weights on some SKUs. The third lever is what shoppers feel without seeing it on the receipt - that is the case PriceActually focuses on.
None of this is unique to J.M. Smucker. The point is not to single out any brand. The point is to make the change visible so you can compare against a competing brand or a store brand and decide for yourself.

How PriceActually flags it
On the Price Checker, enter the current price, current size, and (if you remember) the previous size and previous price. When the new package is smaller and the price is unchanged or higher, we flag it as Possible shrinkflation with the exact size decrease in plain English. We do not single out brands - the rule is the same across every entry.
