That would be fine.
Some years ago you'd hear of potential discriminatory practices in this area. But now there are so many people (54% according to the gov.) using teh Net and that have Net access, it shouldn't be an issue. You can also build the business case that product delivery is easier and more cost effective this way that the pricing is in line with the product costs.
So just as you could offer varying rates from branch to branch for varying reasons, Net rates can be different as well.
