Will radio shack buy my phone 10 points?

Ok I have an HTC evo 4g from Sprint and it work great no scratches dents etc because I had a case and screen protector on it since I purchased it last year the only problem is the water damage sticker turned pink when I layer my phone in water on the counter nothing is wrong with the phone because it wasnt submerged in a bucket of water or anything but I want to get the evo 3d and online there offering me 179 for my evo on radioshack but when I go up there for trade and save will they say no because the stickers are pink. Or does my phone only have to work and be in great condition for them to buy it thank you
