We don't offer refunds on accidental purchases. Purchasing items from our store goes alongside your own responsibility to order the product you'd like to receive.
For Example, if you buy the "Techno & Tech House bundle" and then, in the same order or later, the "Tech House Pack" (which is contained inside the bundle also), is your responsability to check what you are gonna pay for, since the description of the bundles and the pack, is clear with what they have inside.
