I have heard that the "wholesale" cost is about $5.00 (not exact) per bottle.
For each Home Depot to sell $500 per month, they need to move...
$500 / $5.00 = 100 bottles per month or about 25 per week.
Is 25 bottles per week possible?
Lets look at the customer base of Home Depot....
On HD's site they claim... "More than 22 million people visit The Home Depot each week."
22,000,000 people / 2200 locations = 10,000 visitors per store, per week
I think 25 bottles per month is reasonable.
Also, lets not forget the fact that we're being PROMOTED through the "Eco Options program" and could see a high traffic isle display placed in each store.
PS: There are more than 4 weeks (28 day) per month, which makes it a tad easier to reach this per month figure.
365 days per year / 12 months = 30.42 day in a month.
Do the math!
