As far as I know Aldi and Lidl try to use their established business procedures everywhere, because it's cheaper for them. I've never been to the US. But everywhere I've been, the stores all look very similar. I don't know if that applies to bread, but the store layout and product assortment is similar and I bet they also use the same IT infrastructure. Including maybe ePaper price tags that arent that common in some other countries. There are some differences. Some products vary and they don't ship them across the ocean but replace them with local products. And there are cultural differences. For example you can't rip open the plastic wrapper and pull out one bottle of water in some countries. But I bet a lot of it is the same across the world. Especially in Europe.
