Sale 2 is not bulk, it was a gift.

Sale 3 is not bulk, it's untraceable (keys here were likely used to unbox).

https://backpack.tf/item/13809429139 Unfortunately, none of the sales here are traceable. Every single one of the sales here, however, will be above 10 Keys. As not only are classifieds buyers at 11, but stn's buy order is at 11, even when they're selling for 12. Even the untraceable re-dumps will all be higher. 10 is going to be too low here.

This will have to stay outdated until we get a new traceable sale. I'll be closing this as claiming sales are bulk when they aren't is bad practice.
