Baking pro tip for shopping: buy some buckets. 3 gallon is plenty big enough for a grocery store sized bag.

Get the cart to your car, put the buckets (one for each bag of flour) in the buggy and transfer the bag/s into them.

Then move the buckets into your car. They’ll be less messy, protect the paper bags better, and make carrying it in easier via the handles.

If you’re a high volume home baker, it’s still easier than dealing with ordering in bulk.
