Don't think I'd want to call C.S. with these.    Problem with Brookstone is that they are so terribly overpriced that anything for $25 is usually worth about 25cents.    If you have time and patience you can add them together.  Buy something in a store with a GC and return it without a receipt and tell them to add it to your existing GC then do it over and over.  It's a pain in the ass but it worked for me with "legit" GC's I got off a Groupon deal last year so this should be no different.
