I've seen many posts on this already and I honestly think this is something that NEEDS to be included in the Companion App.
The scenario of its values is myself. I'm currently unable to play Destiny on my Xbox because I'm out of town. Today is the weekly reset which means Variks is dealing a different piece of armor, it's the chest piece. The one piece I really wanted from him because I like my other armor pieces now. Therefore I'm unable to buy it, I won't be back for 2 weeks. This also happens to others of course, especially on the weekends with Xûr.
The point is overall quite simple, [b]Bungie needs to add a feature in the companion that allows the purchase of vendor gear strait from your phone ASAP. [/b]
BUMP this if you agree and want this feature.
