You are paying for the SanDisk flash drive itself, the instructions, service of formatting the USB drive particularly to make it bootable for Macs as well as assistance with issues you encounter during installation. If not, you are out of luck but this Recovery kit will help you if you are facing any of the issues mentioned. You can only download certain versions of Mac OS if you had them previously installed on your Mac. Apple has removed your outdated Mac's ability to recover outdated OS.

That’s because they don't want people to reinstall OS X or repair their Mac’s without going through them. Your Mac may not have received an upgrade from Apple or may have had its ability to perform an Online Recovery removed.
