Thanks for the feedback. You make some great points. I'll respond to each.
1. I originally wanted to include the book REMOTE, but figured it'd be better to give customers a choice of books. Then I just opted for the gift card instead for simplicity.
2. I like that idea. I didn't include shipping originally because I have no idea what it will actually cost, and was hoping to offset that risk initially. Totally agree going forward.
3. Just picked a specific niche that I knew it would appeal to in the beginning.
4. Good idea.
