Today from Groupon, you can get a $75 voucher from Wine Insiders for just $25. This is valid for new customers only. I was happy with my previous purchase from Wine Insiders.
Remember, you can still get a $20 voucher to Barnes & Nobles for just $10 through Groupon too!
I would suggest buying your Groupons BEFORE the super bowl ad as they may have server issues once the ad goes live! :)
