I am confused about why I wouldn't change the cogs of items when they cost me more or less....when I place an order, I want to make sure that the price is correct when I get the bill.....is ther a reason NOT to change the cogs on the POS when they change?  Also...how can I change them in bulk...and not have to go into every style, size, color etc to change the price?

Thanks,

Jeannie
