Humble Monthly Bundle Coupons Question

Thank you very much for finding it. I was closed that's why it wasn't showing up for me.

If you scroll down, you'll note that it's not consistant in applying the most recent one, either.

In theory you can just buy it and contact support over it- or if you want to be really safe, contact support beforehand (not like you don't have a bit of time still on it).

Humble Support- despite the disapproval it gets from (a small number?) of people on the forums- is generally spectacular, and very gracious in resolving issues. Well. so long as region-restrictions aren't involved, apparently- though they do give unrestricted refunds for such instances, at the least. It's far more likely that they'll take care of it without issue, than not. :)

The first-time subscriber coupon could be bought for 1 cent, so it's kind of a special promo.

The normal ones seem to be a regular monthly promotion, similar to Groupees coins- they don't really quite make intuitive sense from a financial viewpoint, but they seem to work solidly as a promotion.
Perhaps people are more likely to buy the monthly if they have a coupon for it, and that makes up for any loss.
Or perhaps they're relying on "try it once, get hooked" and aiming toward new customers from the start.
