Group buying using Twitter

I'm not sure but am wondering if we have use Twitter to post information on group purchases.

For e.g a post can be

Buy : Pune : 3 Bed : Kalyani Nagar : 50L

or

Sell : Bangalore : 2 Bed : Jayanagar : 60L

I guess we can gain some traction if there are people and maybe go for group purchases.

I've created a twitter page IndiaBubbleApt
