[DISCUSS] Can't we get completed GB's

Hi moderators
I dont know where to post this,am writing it here

why cannot we get the completed GB's for same price as seat sold in original GB

It has got advantages
1)time is an important factor especially for us ,so it saves a lot of time for those who need it urgently unlike forming an other GB which takes a lot of time.
2)generates revenue for site/moderators-after all you deserve it.
3)work of moderators will some what decrease,i think.so can concentrate on new GB's

if some one wants an updated material of an old GB then they will form a new group to buy n rip the latest.

so i request moderators to make this option available in the site.

I dont see any disadvantages in it,i dont know why this option is not available.
