You're one of their members, specificly a anomalous one. Hopefully, you're too valuable for them to sell you

You have been sent with a group of seven men in business suits (as well as you do) holding briefcases with multiple on sale anomalous artifacts

After a while, a wealthy man arrives to the location of the group (and yours), shaking hands with one of the members before thanking with an british tone "As I promised, here is the money. Use it wisely, and thanks again." He handed a half million dolars to you with a slight smile on his face
