Nope! You can and should use the same suppliers you know and love. They're fully compatible with Vetcove. You also keep your reps, and they get compensated the same exact way (ie. they still get their commissions from your orders).  All orders are still placed onto your account with your vendors directly, so pricing, delivery times, or other logistics are not affected at all. The only difference is that you're using Vetcove as a tool to do your research, shopping, and checkout, making the whole process smarter and easier!
