Pop Up for my home page

I just need a simple stack that will allow me to pop up a ‘Hurry, buy now by clicking here’ type message with an image.
What do you recommend?

1LD’s Notice stack works well.


Thanks Rob. I actually went with 1LD’s PopBox RapidWeaver Stacks by 1LD | Professional & Free, Responsive & Modern.
Working out pretty good. Though I’m not quite sure the difference between it and ‘Notice.’
