Title says all. When someone for example buys the 3 home point upgrade and someone else buys the 5 home points upgrade we should get 8 home points instead of 5 why this should be added? 2 reasons. 1. This will boost sales in purchase of home points upgrades because if people know they can stack em they will buy more 2. This will not make a lower tier upgrade of home points go to waste remember people do spend money on these and it will be insulting if they would effectively be useless.
