Deer slugs

Has anyone seen the price of deer slugs ?? Season here in Ohio is end of November so thought I'd pick a few boxes up before they become nonexistent. I usually have to supply my boys lol but they supply venison to me. Anyhow cheapest I found was at wally world were 6.98 federal box of 5. Others as winchester was 8.97. And Remington sluggers were 9.97. All 5 round boxes. I was like wow! So instead of 20 boxes I normal pick up before season, became 4 boxes lol work on a few more later.
