Instead, I flip the script — when I’m about to make a purchase of any sort, I go to my favorite podcast’s home page and see if they’re offering a deal on that item. It helps me save money, and it helps support the podcast without buying stuff I wouldn’t otherwise be buying.
One of my favorite podcasts (the Jordan Harbinger Show) also has a comprehensive “deals” page with discounts on everything from bras to bedclothes and everything in between: Jordan Harbinger’s Deals page. I just get in the habit of checking that page before making a purchase (the last one was bedsheets if you must know!)
