Casinos could offer those things on their platforms but I don't know. I just don't know how.
E-commerce shipping is a simple means of sending gifts or items to people around the globe, they can reach out to companies that has gift cards like Amazon and colloborate with them to enable a giftcard package or better offer gift cards to members of their slot clubs to enable them buy whatever they need on such platforms. No need for free hotel nights as someone pointed out, if not I would have also recommended some hotel like Marriot that enable worldwide bookings.
Well, they're no comparisons, its just like comparing the bank to bitcoin in terms of existence and money made from people. Yet the online casino is not as strong as the offline casino regarding age and government connections. Though nobody knows if the market would change in future, nothing beats giving back, no matter how little, to players these are practices that can boost the online casino's audience.
But I guess those who play gambling in online casinos may not need such things.
Alternatively, online casinos can provide something different from offline casinos, such as giving bonuses or free spins to loyal customers.
And I think so far, online casinos have really tried to satisfy their customers with various attractive offers, which of course, have attracted many gamblers to follow them and try to get them.
Each casino, whether online or offline, has its own way of satisfying its customers and will apply it in many events.
And I'm sure online casinos can also develop well even though they don't implement things like offline casinos.
