Do I need an account to buy?

Not every customer wants to create an account first, and that is understandable. The important thing is this: whether you order with an account or not, you must enter your email address carefully and make sure your shipping and billing details are correct before completing checkout. Your email is the main link between you and the order, especially if there is a need to confirm details, send updates, or resolve a problem. If you prefer having a place where your order history and account-related actions are easier to manage, creating an account is generally the cleaner option. The main navigation bar includes a dedicated Account area.

Logging in is required for some public actions, such as asking or answering questions in the FAQ area. So even if you are just browsing at first, having an account makes it easier to interact with the site properly. 

If you plan to buy, ask questions, or come back later to the same project, creating and using an account is the safest approach. It keeps things simpler and avoids confusion later, especially if you need support, want to follow up on an order, or need to interact with the site again.
