I’ve used both Groupon and Living Social. Many of my current clients came to me through one or the other. The majority of those who take advantage of these coupons are there because of the great deal, and plan not to return if they have to pay full price. However, if the service you provide is valuable enough to them, they will return. To make it more enticing for the coupon holders to return you can offer “discounts” for signing up friends, or for couples memberships. I was careful to word the Groupon and Living Social ads to state NEW PARTICIPANTS ONLY. Which prohibits habitual bargain hunters to keep coming back. I also made my coupons good for 3 months, not the 6 or 12 that was “strongly” suggested. If a coupon holder asked for an extension, I offered a slight discount but did not honor the coupons after expiration. I found working with Groupon and Living Social members to be ultimately worth the effort.
