From experience of local business - online shopping is profitable because seller does not include rent, bill and stuff like that in the price. Moreover, most of them dont even have warehouses, and perform as intermediary only.
Why the rest are still high? I can only suppose that owners are just greedy. I dont know why, but in our town owners prefer to have an empty room instead of lowering price and renting it. They used to 35-45 EUR/m2 and dont want to get any lower.
Generally a company will run in a hybrid manner, namely between online and offline..because both of these methods have their own advantages... casinos are the same, when the potential of online casinos has better opportunities, a bookie will try to get the market there... and it is proven that online and live gambling has many fans...
We are indeed in a transition period for several sectors, from what was originally very thick with offline culture, now starting to move slowly to online culture... and gambling has a greater opportunity when presented on an online platform..
the internet and gadgets have really changed this habit.
