How do I get back something I put on Spam by accident?

Go into TOOLS (I assume you are talking about IE) and then INTERNET OPTIONS and select the PRIVACY tab ... see the button that says SITES, add overstock.com and ALLOW it.

If you are referring to your e-mail, go to the SPAM folder and mark it as NOT SPAM ... you will get a confirmation pop up for confirmation, and then you should be seeing any e-mail you get from Overstock in your regular in-box.

I'm supposing you're using Yahoo! Mail, in which case you can do two things:

1) Add overstock.com (try to find an e-mail address on their site) to your address book, so any mail from them will be sent to your Inbox, rather than bulk.

or

2) Wait to get an e-mail from them in your Bulk Mail, then open the message and click "Not Spam."

Hope that helps!

It is possibly in your deleted folder
