How much are you asking?

Not really sure?? They will owe me about $5 landed in AU

Padded bag = $1.00
Anti-static foam and anti-static back packing = FREE (gee, I'm a nice guy)
Post = $1.20
cost = ~$5

Total cost = $7.20

Is $10 for one - $15 for two unreasonable????

I wouldn't sell more than 2 pcs to one person as I would rather share them around
