6. Make sure you check the shipping policy before you buy anything. Many online retailers offer free shipping, but sometimes it comes with a catch - like a minimum order amount.
7. If you're not sure about a store's return policy, give them a call or send them an email to ask. Most online stores will allow you to return items within a certain time frame, but some have stricter policies than others.
8. Be sure to choose a store that accepts the payment method you're most comfortable with. Some stores only accept credit cards, while others accept other forms of payment.
9. Trust your gut. Ultimately, you should choose the book that feels right for you. If something doesn't feel quite right, don't force yourself to read it. There are plenty of other great books out there!
10. Take your time. There's no rush when it comes to finding new sci-fi books series to read. So, take your time browsing, and don't feel like you need to make a purchase right away.
