Sometimes they do. However, it depends on the specific Walmart store and their current inventory. Some stores might have a better comic book section than others.
Well, it varies by location. Some Walmart stores have a decent selection of comic books, while others might have only a few or none at all. It's kind of hit or miss.
Another option could be to check with Walmart employees. If you're in the store, ask someone at the customer service desk or in the book section if they can help you locate specific fiction books or if they have any new arrivals in that category. They might be able to point you in the right direction or even let you know if there are any upcoming sales on fiction books.
Often, the self-help or educational books area in Walmart could have what you're looking for. Check the shelves labeled with writing or literature-related tags.
Walmart bedtime stories could potentially be stories that are somehow related to Walmart. Maybe they are stories told by Walmart employees to their kids at bedtime, or perhaps they are stories inspired by the Walmart shopping experience. For example, it could be a story about a child going on a shopping adventure in Walmart, finding different toys and making new friends there.
