Vulcan has some kettlebells on sale, and some dumbbells on clearance.
https://www.vulcanstrength.com/"Vulcan Strength Training Systems is a veteran owned business and greatly appreciated the sacrifices of US military members and families. The Veterans/Military discount is 5% off regular priced products. The discount does not apply to items listed as on sale or items that are not Vulcan brand products. The discount must be applied at the time of purchase."
Rep Fitness hasn't been mentioned yet.
https://repfitness.com/"Since our founding in 2012, REP has offered a 5% discount to first responders, active military, and veterans. Our respect for those who provide our freedom and security is what drove our desire to give back. We still hold that same respect today, but in 2023 we have chosen a more targeted approach to giving back. Rather than a discount to everyone regardless of need, we have chosen to pledge $100,000 to three great charities that help military and first responder's families. In this way we can ensure the money we give goes to those with the greatest need, and continues our tradition of honoring those who serve our nation and our community."
If you go the Amazon route, you could use
https://camelcamelcamel.com/to try and catch a deal. I do feel like there are some Facebook Marketplace/Craigslist deals out there, but you might not have the time to hunt for them. After COVID, I feel like fitness equipment is similar to housing or vehicles, they are more expensive, and the deals do not seem to be as good as they once were.
