I got my journal from CadenetaNotebooks on Etsy. They're a great option if you want lots of colors and sizes to choose from. Depending on the journal, they'll also work with you to do some ~customization~.
You can also get this Traveler's Notebook bundle from Amazon for $25.97. It's made of ~real~ leather and includes three notebooks, a pen, a card holder, and a zipper insert — basically everything you need to get started.
