Coin Sale

Hey, I want to donate for some gear for my paladin so I just want to ask when will be the next coin sale?

It varies, and honestly I think that its done when donations go below a certain level.......But I don't know for certain, however, most years they give out bonus coins in the form of x-mas gifts if you donate before a certain date... which should be approaching soon, so now would be a good time I feel.

I would wait til this coming holidays. There is very likely to be some sales or gifts or promotions. If you can't wait, well, buy now, regret later, or get your fun out now and you might not be playing later anyway because you got a different gift. That's life.
