Take a picture of it with your phone and post it here, we'll give you lots of opinions on whether to try to rescue it.
I only rescue the ones that look fairly good, Cameron. If the leaves are shriveled, but still have a little bit of shine, there's a chance it will revive, but if they are dull and dry, and feel hard when you squeeze them, give it a pass. Also look at the roots if you can. If there are fat, white roots or shiny roots coming out the top of the moss, the plant is still trying to survive.
I'll also sometimes gamble on a big plant if they've marked it down to under $5 or so.
