Groupon takes an extra 20% off up to three local deals or up to three goods via coupon code "SALE3". It also cuts an extra 10% off up to three getaway deals. (A maximum discount of $50 applies per deal.) That's one of the best discounts we've seen from Groupon this year. (We saw up to 25% off four weeks ago, however it was limited to just local deals.) Deal ends April 28. Some exclusions may apply.
