Hole in wall of liner in underground pool?

We have a large underground pool. About a week ago, after opening it for the summer, we discovered a small hole in the wall of the liner in our pool. It's not so large, but its deep enough to drain more than an inch of water from the pool after a day. It's been doing this for a while now, and I'm desperate to get it patched up as quick as possible. I researched about this online and learned that I should buy a vinyl patch repair kit to get it fixed. However, I don't think I'll be able to be able to go out and buy one, at least right now, and ordering isn't an option, since I'll be getting the repair kit by Wednesday since there will be no deliveries on Monday (4th of July). So does anyone know of any do it yourself at home remedies that will allow me to patch this hole up in the meantime? I know tape won't work, but if you guys have any ideas on what will, please let me know!
