From an email that appeared a few hours ago:
- Find any deal you want of $30 or more.
- Click the Buy button before August 25 and your Groupon Bucks will automatically get an extra $10 boost at checkout.
Obviously this is a personalized offer, so check your own emails (especially the SPAM folder) to see if you got this great deal. The Groupon Bucks mentioned are credits in my account from a deal I cancelled after purchase, which may or may not have a bearing on this email.
