Sheepie, I told ya to c & p. S'ok - I'll do it for ya -
Who would know? No-one here is able to tell you when they might happen. Best thing to do is keep an eye on the forum because if a promotion comes up, someone always posts a link.
This year they've been happening every 4 weeks, so if that pattern continues, then this weekend will be the one. Don't hold your breath though because they are becoming less frequent.
There ya go 
Thank you, thank you, Ladies and Gents - I'll be here all week
Spoiler
I can hear the collective groan
