Grocery Store Brands

Okay, I know Stop & Shop and Giant have been owned by the same company for quite some time now (stupid Dutch), but is it really necessary to make them identical right down to the smallest detail? At that point, why do they even have different names? And why does Giant-Carlisle get off scot-free from all this homogenization? It's owned by the same evil Dutch company!

Hmmmmmmmm....
