Liquid Test Kits (expire?)

[atmmachine816]

My lfs is having a awesome sale and I just picked up a aquarium pharmauticals master test kit for 7.50 and was wondering if these ever go bad, because if they don't I think I'll go pick up another one since it's a great price. I don't see any expiration date so if anybody knows please let me know?

thanks
