I popped by my local Walmart and they were baffled. Had never heard of Kobos. I had to tell them about their own ✲ebooks website page, show them the Walmart ebooks app.
It was funny. They suggested I try other, larger Walmarts that might get new products like that first. The Walmart electronics manager claimed that they were phasing out tablets altogether. But lower level management only knows what upper management tells them. I'm sure they'll get the Kobos one day soon.
