Since Groupon bought out rival LivingSocial we’ve seen a few similar deals posted on both sites. LivingSocial now has the same deal that Groupon had for Dunkin Donuts lovers. Pay just $5 for a $10 Dunkin Donuts eGift Card.
Sadly, this offer is only only available to those who received an invitation, but you could still check I guess to see if you were targeted.
These deals have a limit of 1 per person, but hopefully some will be able to get them on both LivingSocial and Groupon.
Also go through a shopping portal for your purchase. Mr.Rebates have the best rates right now with 8% cashback for LivingSocial deals.
