Which means within 90 days...returns/exchanges/refunds etc are done in-store. After that time period then the customer would need to deal with the manufacturer for any warranty issues. Some other items are less then 90 days but by reading the policy it dose not seem to apply to a blender.
As far as needing the box for a return..it is not stated in Walmarts policy so I can't see why they should refuse a refund. A restocking fee is also not mentioned such as with other companies like BestBuy clearly state in the return policy.
Return Policy
Walmart's Return Policy
Customer satisfaction guaranteed by repair,

As an added convenience for customers, Walmart has adjusted its return

purchased between Nov. 15 and Dec. 25, the limited return period will
begin Dec. 26. This includes items such as TVs, cameras, computers,
DVD and music players which can have a 15-30 day return period.
