Music Shopping

So, I'm doing some comparative shopping for music online. And it's ridiculous!
amazon.ca has A.C. Newman's "Get Guilty" for $12.99. It's $18.99 at chapters.indigo.ca ! Six dollar difference!

EDIT: I clicked the wrong site. It's $12.99 (USD) on amazon.com, and $22.99 on amazon.ca . So there's still quite a discrepancy.

Any good concerts coming up? Joel Plaskett is releasing a new album in late March. I'm excited.
