Can I buy bags from Aldi?

Excuse me, I was wondering if I could clarify something about purchasing bags from Aldi. Is it possible to buy bags specifically from Aldi, or do they only provide bags for a fee at checkout? I'm interested in knowing if Aldi offers reusable bags for sale, or if there's a policy regarding bringing my own bags for shopping. Additionally, I'm curious if there are any discounts or incentives for customers who choose to use their own bags during shopping trips. Thank you for your time and assistance in clarifying this matter.
