This is not a good deal FOR THE GRIL. An average (cheap) 3 pack toothbrush set in Korea costs just under $2 USD (1.89), so at this rate she is only making $3.11 USD in profit for each sale. Assuming each male is not dumb enough to buy twice, she will quickly exhaust her customer base and go out of business. This is unless she invests heavily in marketing to affect the market. If she is selling even midbrand toothbrushes, she is loosing money. Hemorrhaging. The cost alone is $15-16 US. This is all assuming she doesn't find the sickos who would love a Domi Toothbrush Mommy.
