Doesn't look like this has been updated in a couple years so just logging I paid 169 keys. If I missed anything I need to include, let me know but mostly just wanted to log as a reference.

The compare isn't clean as I traded others hats the same day and keys I bought from mannco don't appear so screenshot also included from Steam inventory.

I know it's not easy to tell but that's 56 rows of 3 keys (168) + 1 = 169.
