They are just adding random items "swag" to random orders of preferred reefers.
Giving out everything from Apex's, to Sicce pumps or internal filters and more.
the stuff they are giving out daily in free items is usually in their Youtube "Shorts" section
Stopped by to pick up 2 orders today and found a Sicce Shark Pro 500 in my bag and also got a free long handled glass scraper offered to me as I walked out. Got my 2x mystery cards too, so that's at least $20. Thanks BRS!
