Stay with Net Driven if
Stay with Net Driven if co-op dollars are paying for it. When your distributor program only releases those funds to approved vendors, the site is effectively discounted or free to you, and no independent shop can beat free with a lower monthly fee.
Stay if you need live tire inventory and pricing on the page. Feeding a tire catalogue with real stock and prices from your distributor is specialist plumbing, and it is not something a general website shop can rebuild for you. If customers are quoting tires on your site today, keep it.
