It's not too difficult to get a Store delivery driver job as long as you have a valid driver's license and a good driving record. If you want to use your own truck for deliveries, you can inquire directly with the store about their requirements and any opportunities available. You can also search for delivery driver positions on job search platforms like Jobcase, Indeed, and Craigslist. Make sure to highlight your vehicle's specifications and your prior delivery experience on your resume. Good luck!
