Sept party reload?
 

Just had one the other day with bonus code "USETOWIN" but I don't think this was the monthly. Is there a September one out yet?

I don't think there will be one. Party had several bonus codes, all account specific or random last week, so I doubt they will have a monthly one.

I am all over it if they do though ;) .

I saw on bonuswhores BONUSSEP - havent tried it yet though.

That was one of the many released on September 1st, others including USETOWIN (that's what I got), and REALCHANCE. I'm hoping later this month but don't get your hopes up.

I had USETOWIN as well...

And they are not stackable
 

At least for me. I tried multiple ones, and only the one I saw on the pop actually worked.
