In the UK it's £3.60, which is nearly $5!

Wowww ok, mea culpa maxima, I should not feel so bad. I would send domestically but the international cards are so much more interesting to me.

The cost varies a lot by country, yeah. It can be more expensive like the UK or cheaper like in Japan ($0.65).

In Denmark, 46DKK ~= $7.15.
