Kobo has a store. It's decent, it won't have Kindle indies, and IMO it has fewer/worse sales, but it's not a big deal to me. They do have a subscription plan with unlimited access to certain books but it's not clear to me how good the catalog is.
You can also buy from third party stores, e.g. Weightless Books for sci-fi & fantasy, and just drag-and-drop the epub onto the Kobo.
Just checked kobo sites due to original comment. The catalog may be smaller but now they (India store) have comparable book prices to kindle. The last time (many years back) I checked, books were not available in India.
I had first edition terrible keyboard kindle and have a paperwhite. It seems libra colour is still not available in India.
What bothers me with drag and dropping epubs is that you can read it fine and annotate but I can't find the annotations online. I haven't even looked up exporting the annotations manually from the device because that is not my scenario.
