I just posted this in another comment actually lol

“ I was apart of the e-commerce supply chain. They actually lose more in online sales than in store. Brick and mortar is what they thrive on. I may be recalling the quote incorrectly but, an American (on average) is no more than 6 miles away from a Walmart or Sam's Club. It’s actually kinda creepy when you think about it.”

As for the breakdown of the split, I’m not sure. I do know that most e-commerce warehouses are not profitable for the first 3 years. They use a model similar to amazon where the expansion plan is to have a warehouse in an area that covers parts of a state. I know California has most of them in So-Cal with one or two in Nor-Cal. It also depends on what type of facility it is. The shipping for large items such as bbqs and tvs vs small items like toys and personal items is what will determine the length of the timeline to profitability. If it’s a hybrid building it’s a crapshoot and all bets are off.
