I use Clear Care. It was recommended by my doctor last year and at first I thought "what difference does it make?" Let me say, it makes a HUGE difference for me. My contacts used to get dry during the day and I'd have to use rewetting drops regularly. And I would take the contacts out as soon as I got home.
Clear Care isn't regular saline and I don't believe there is a store brand. You can't just use it to rinse your contacts. The contacts have to sit in the solution for at least 6 hours before you can wear them again. It does contain 3% hydrogen peroxide. But it works. My eyes are almost never dry and I hardly every use my rewetting drops. I do have some regular saline also just in case I need to rinse a lens and put it back in, but for overnight cleaning, I only use Clear Care now.
It also comes with it's own case, which is completely different from any case you've seen. It is definitely more expensive than regular saline, but if you want to extend the life of your lenses and improve the feel of them when wearing them all day, Clear Care is the way to go. (of course I must say, I am not an eye doctor, so it might be a good idea for you to consult with your own doc before trying it.)
