I purchased a salad dressing (Trader Joe's brand) for $2.99. The bottom fell out in the car. Can I get a refund or replacement?

Of course, just come on in and grab a new one.

Go ask them. They are usually pretty helpful about stuff like that. Bring in the parts of it to show them what happened.

Trader Joes is pretty good about that sort of thing. So I would expect them to either refund or replace it for you, no problem!
