It happens. The wrong item gets sent. The package is damaged in transit. It doesn't arrive at all.
After shopping online for a few years, you will probably have experienced all of these situations. I have, so I know how frustrating it can be. If something unforeseen happens to your order, I will do everything in my power to make it right.
Just use the contact form here in the store, or email firstname.lastname@example.org and explain your situation in as much detail as possible. I'm a solitary human being, not a big company, so it is especially important to me that your experience be a pleasant one!
