FYI: Some may have noticed Mint Retrograde's perks have switched from very premium rolls on Tuesday to low quality rolls on Wednesday. Zavala is bugged. It does NOT change daily. This is an old bug where a vendor sets perks on Tuesday, then resets perks a 2nd time lasting through end of the week.

The "god rolls" are no longer available. A forum post has been started here, comment for your support: https://www.bungie.net/en/Forums/Post/265009421
Why this is an issue: not everyone understands this bug exists before investing (if you missed the prior week of gameplay to auto-unlock Zavala's inventory).
This is something Bungie had to correct with other vendors in the past—but Zavala specifically doesn't let you preview the reward until spending Bright Dust.
