Jon,

There are any number of sites that run sales, apparently at random. And too many to make it worth tracking, unless you'd like a 2nd career. The first two or 3 are ones worth watching, for different reasons: cdkeys.com   humblebundle.com  scdkeys.com gamesplanet.com gamesdeal.com  gog.com (oldies)

And, of course, ubisoft has its own site, and sometimes runs its own sales. As does steam, altho I haven't found great deals there.

One also might look on ebay - there are often codes for sale there.

I gave in and bought an Xbox One X. No regrets - it's everything they say it is. Microsoft finally does something right. Ought to be front page news.

Now answer me a riddle: Why is Trump crushing this market? Doesn't he realize it can do it all on its own?
