LCD Screen Protectors

My husband has been looking for an affordable screen protectors for his digital camera. He found one on EBay for 20$ per pack which only has 2 LDC Kit. I think it's way too expensive compared to what I've paid before when I bought one pack for my cell phone. Amazon has one for $2.80 but I'm not sure if this one is what we are looking for.
Screen Protectors are great for cell phones PDA's or navigation systems. It protects screen from scratches wear and damage. It also reduces screen glare and improves contrast .
