When it comes to buying mystery books for 10-12 year olds, there are a few things you need to keep in mind in order to get the best possible deal. The first thing you need to do is set a budget for yourself. Decide how much money you are willing to spend on a book before you start shopping. This will help you narrow down your choices and make sure you don't overspend. Keep in mind that many stores offer discounts for purchasing multiple books at once. So, if you're looking to buy more than one book, it's definitely worth checking the store’s discount policy.

Another option to get the best deal on mystery books for 10-12 year olds is to wait for sales. Major retailers will often have sales on popular titles a few times per year. By waiting for a sale, you can usually get a book at a significantly lower price than the regular retail price.

Finally, it is important to think about where you will be reading the book. If you plan on reading the book primarily at home, then it does not make sense to spend a lot of money on a hardcover edition. However, if you plan on traveling with the book or taking it to the beach, then spending a bit more money on a durable edition makes sense.

Here are a few tips to help you buy the best mystery books for 10-12 year olds:

1. Look for well-reviewed mystery books for 10-12 year olds. Checking out what other readers have said about a book can give you a good idea of whether it's worth your time. You can find reviews online or in newspapers and magazines.
2. Consider the author's reputation. If you're familiar with an author's other work and liked it, there's a good chance you'll enjoy their new book.
3. Think about what you want to get out of the book. If you're looking for a light read, something funny, or a book that will make you think, you can narrow down your options by looking for books that fit those descriptions.
4. Check the price. Sometimes, you can find great deals on new mystery books for 10-12 year olds. But be careful of cheaply made books, they might not be worth your money.
5. Take a look at the return policy. Some online stores will not accept returns on certain items, so it's important to know what the policy is before buying anything.
6. Ask for recommendations. Talk to your friends, family, and fellow book lovers to see if they have any suggestions.

By doing all of these things, you can be sure that you're getting the best possible deal on mystery books for 10-12 year olds when you shop online.
