Hi all, I love the SGP and Powersupport screen protectors but it's tough to justify buying a close to $30 sheet of plastic. I use SGP on my iPhone and have previously used them on my iPad. IThrough.com had a great deal on the SGP screen protectors for the iPhone 4 (like $4 a package). Are there sites that run a similar deal or that have a comparable matte screen protector that's cheaper? Thx.
