Why don't all of us who would like an Aldi email them, via the contacts address on their website, and ask for an Aldi in Marple (giving your reasons why).
That way, they could gauge the level of interest and maybe look a 'little more actively'.
I'd certainly welcome one.
Aldi have just been granted permission to build one in Chapel-en-le-Frith. Let's try and beat New Mills and Whaley Bridge before they try getting one.
