I was looking at shipping prices as I was thinking I might be able to help out with some proxying. International priority shipping on Gustin's site is showing $23 for me. A 2 pound priority package from US to Canada would be $28 (that's online discounted price too). So it seems like Gustin's actually giving a discount. With domestic shipping $5, and 2 pound first class shipping to Canada at $15, there's really no benefit of getting it proxied (and is just slower in fact).
