Slow cooker meats?

Hey all, been looking at YouTube slow cooker recipies on YouTube and I know meat over here is super expensive, but does anyone know if some of these cheaper cuts exist? Colesworth never seem to have any these days, and I think I’ve only seen gravy beef once at Aldi which I’m guessing is the best thing. Any idea where I’d get something that’s happy to site in the slow cooker for 8 hours that won’t cost me a kidney?
