Bring resume to stores or fill applications?

Always Always Always bring a resume ! If they refuse it than at least you tried but a resume usually has more specific details about yourself and your work experience (even if you've never worked before, any volunteer work should be on there too) that may set you apart from the rest of the aplicants. Also always dress profesionally when you are job hunting. It shows your mature and serious about being hired.

You could take one so you can use it to fill out the application, but places like that will need the application completed. You can't just put "see resume" on the application.

If you are looking for your first job you don't really have much to put on a resume anyway.

Most companies turn towards more online applications nowadays. I would apply online anywhere that has online applications. A week after you apply online, it doesn't hurt to go apply in store either to make yourself look good! Some companies like Petsmart for example have a no paper trail policy,(in Canada anyways) which means they don't accept in store resumes!
