For select customers only, Groupon takes $10 off orders of $20 or more, $20 off $40 or more, or $30 off $60 or more, including already discounted items and local deals, via coupon code "SAVEMORE". That's among the best and widest ranging discounts we've seen from Groupon this year. Shipping adds $3.99 where applicable, but orders of $35 or more bag free shipping. Some exclusions may apply. Deal ends September 18.
Note: This had been a general discount for everyone, but Groupon has since restricted its use. (The terms of the restrictions are unknown.)
