I want to upgrade the OS on my iMac. My internet connection is not the best and downloading the update takes a very long time and often fails. I have a Retina 5K that is running High Sierra (10.13.6) and wish to upgrade to Mojave. Is there any place I can buy the software on disk or on a memory stick?

The Mojave App Store link is in this Apple support article:
How to get old versions of macOS - Apple Support
It will note show up in a regular search of the App Store.
Two tips:
1) Use Safari for any downloads. Firefox is not working properly with Apple system downloads.
2) If you see and error about a "damaged" file, that simply means that the current installer found an older and out-of-date version of itself. If so, the old one is in your Applications folder. Delete it.
It can only be downloaded from the App Store.
Try downloading while in Safe Mode.
