Guys! I am just wondering how this have affect your local business?!

One customer who used to buy from us now buying online :

Canon 104 ... $30 each
Canon 106 ... $44 each

of course, I am not sure about the quality of them thu.

Since the economy is bad, have you guys, as local refill stores, been affected by these online pricing??? How do you calculate your pricing then? We offer 40% off retail on these models.
