What is the Walmart employee discount?

Can you please elaborate on the specifics of the Walmart employee discount? I'm curious to know if it's a fixed percentage off all purchases, or if it varies based on certain criteria. Additionally, I'm wondering if there are any restrictions or exclusions on the types of products that the discount applies to. Finally, I'm interested in finding out if there are any additional benefits or perks that come with being a Walmart employee beyond just the discount. Thank you for your time and assistance in answering these questions.
