I believe we should have a 10 minute window to refund armor for first attempt purchase during its rotation. resets when rotated out and back into the shop . Also we should have an unlimited amount of refunds so long as its your first time buying the individual item during that day.
unlimited in the sense of you can buy everything in shop and get a refund for all of it then next day buy the new daily.
we should also get 3 yearly refund 30 day tickets kinda like fortnite.
