text: As long as there is no stipulation that the card is non-transferrable, you can try to sell it on ebay.  My guess is that you won't get anywhere near the cash value of it because it's insanely rare that anyone gets gift certificates for that large an amount especially on groceries. You will then be further limited to hoping to find a buyer among the people who have access to that particular grocery store or chain.\n\nThere are also a few websites where you can sell gift cards or exchange them for gift cards to other stores and although they were discussed in the news for a while, a great number of people still don't know they exist so again, you'd be hoping for a buyer from a small scross section of people.\n\nWith a certificate that large, in my opinion, the only way you can get the best value out of it is to just use it yourself over time until it runs out.
