Groupon has a promo code for an extra 20% off local deals, 10% off Getaways and 10% off Goods! This is today only. You can use the 20% off promo code on local spas, restaurants (a great way to try new places!), hair salons and so much more! If you have kids, Sesame Street Live is a great choice (shows up as a local deal for me, probably in select cities). The tickets are $14, so with the promo code they would only be $11.20! There are also some fantastic travel deals (some even include flights) that are even better packages after the 10% promo code!
To get this deal, use the promo code SURPRISE at checkout. The maximum discount you can get is $50. You can use this code three separate times but only once per transaction (so if you are buying more than one Groupon make sure you check out separately to get the discount on more than one deal). This promo code ends at 11:59pm EST.
