Unfortunately in today's market I don't have any particular place I shop. I just keep my eyes open and look for in stock items and use my phone to check prices. It's getting better but too many places are either priced rediculous or unreliable at either being in stock, or showing in stock only to send you an email with a backorder.
As far as reloading, it depends on what you already have. I purchased my first reloaded in 2020, right before things went nuts. Been slowly piecing together everything I need. But once you factor in the cost of the basic components you need, plus powder, primers, bullets and brass, it's really not worth it price wise. Biggest driver for me is to hopefully be as self sufficient as possible, along with being able to consistently have ammo for harder to find calibers.
