Are Amazon returns allow d by this store?

No, whole foods is owned by Amazon but is still a grocery store. There is an Amazon locker in the store but you can't just up and return Amazon products

Yes

Call the store

I doubt it, you have to process returns thru the Amazon website, and to date returning to Whole Foods has not been an option

That's a good question

I do not know about amazon return allow in the store but you can go in front of the store and ask the person who is working in comstor seveice that day.
