7

10 (2x, marketplace)

3 sellers for much cheaper than the marketplace sales at 10. Excluding 10.

The buyer of the 7 key sale re-sold to a bot for cheaper. Excluding 7. Would've included it regardless of it being re-sold to a bot if it weren't for the seller for less than 7 keys currently, as I'm using the price it was sold back to a bot for in the range.

Altogether, there are 6 gladiator purchases around 6 keys, 5 of which were in the last month.
