Focus Camera via Rakuten Shopping offers two Sony 16GB Class 10 Secure Digital High Capacity Memory Cards, model no. SF16NX/TQ, for $17.95 with free shipping ($0.56/GB). That's $9 per card and $8 under the lowest total price we could find for a pair of these memory cards elsewhere. (However, we saw a 2-pack for $3 less a month ago.)
