Untapped market...
HAHAHAHA
Have you ever been to japan?
Walk down the street and you'll see every vendor has at least 500VCD's ready to flog off...
Then you've got the vending machines ready to sell you 'used panties'
Trust me, do yourself a big favour, head over to tokyo look around, then tell me it's an untapped market.
Oh and also
