I am going to rent a car and go skydiving
Don't you need an airplane for that? Maybe that's why it's so cheap- it's not a very far drop. Also, "cheap as it gets" doesn't sound like the way I'd like to jump out of an airplane. Sounds like they grabbed some thread and stitched together some old parachutes they found in a dumpster behind the parachute factory. I don't mind paying a bit extra for an item that allows me to land on the ground in my regular, human form and not in a pile of blood and guts and bones. Also, I'm afraid of sky diving.
