Does anyone know somewhere where I can purchase a single replacement key for my Toshiba A305d Laptop? - toshiba keyboard replacement

I bought a new Toshiba A305D-S6848 from Best Buy, there are some time .. and my dog went BUTTON (and, or he has eaten or lost because I did not) find it ... I need to buy a spare key. I do not want to buy a new keyboard, and I do not want a sack full of keys ... Only the title arrow key. Ideas?
