If you're planning a visit to Brookgreen Gardens in the next few months, they are currently running some deals available thru Thursday 3/20. After purchasing, you've got 90 days to use the coupon. The deal is two admissions for $14 or four admissions for $25. Tickets are normally $14 each. Tickets can be used for 7 consecutive days.
I have found dealsaver good to deal with, but pay attention to the details. For example, the two-fer deal does not permit you to use it twice as an individual. It's good for two people visiting the gardens at the same time. For those who have never been, it's a beautiful place and you won't get a better deal.
