Comes with the stainless steel multi-level rack. Seems better than the Walmart version because everything gets noticeably crispier and more even.
For anyone debating Walmart $40 vs Costco $50 total: there's a good Reddit thread comparing the two models side-by-side: https://www.reddit.com/r/airfryer...8qt_
Most people say the Costco one (2024 model GAF858) is worth the few extra bucks for the rack, assembled handle, and 450°F max temp. If you're a member and can grab it in-store you save the $5 shipping too.
Solid deal if you need a big 8 qt with a window.
