Hi there - You may find Woot’s refurbished guide to be helpful:
Below is a link to Woot’s return policy.
https://www.woot.com/faq?ref=w_ngf_rp#what-is-woots-return-policy
Unofficially: Woot will help you out, unless you abuse the return policy.
(Please note: I don’t work for Woot, I just volunteer to help out here on the forums.)
