I was just looking to activate my recently-purchased copy of Ableton Live 10 Standard from eBay for a good price of $460 when I discovered they now have their own special deals available for everyone who has a copy of Ableton Live 10 Intro.
The Intro edition of Live 10 comes bundled free with various audio recording/production gear such as audio interfaces (to connect XLR microphones to a PC) or MIDI Controllers/Keyboards. It has a few key restrictions though so this is a good opportunity to upgrade at a discounted price.
Review their Store page to compare editions.
NOTE you may have to login with your Ableton account to see the discounted upgrade prices.
Expires 3 September 2019
Hope this helps - first submission from me.
