Well, that's two 1s on my shopping trip, sadly neither for the Null Rod where I needed a 3 or less.

Summary of certain purchases: Blessed Edge on all melee weapons Macharius and the Praetorians have, Condemnor bolters for the Praetorians, at least a common-quality witch lance, an Eos Star Amulet, and Rosarii for the Praetorians. The Emperor felt extremely strongly about the bolters and Rosarii. Praetorian quipment is only enough for the 5-man team, not the eventual 100. They can live with regular bolters and no force fields.

Rolls where Opposed Commerce might matter: psyk-out grenades for both him and the team, better-quality witch lances

Definitely no: the Null Rod :(
