I bought a load of DAHLIAS cheap at the store.. i planted them ...?

Question:so my question is... anything special I need to do? Do i dig them up for the winter so they can grow next year and transplant them?

Answers:
Depends upon where you live. If you have mild winters, you can leave them in the ground. If your winters are severe; then dig them up and store them in peat moss or sand until next season. Keep them cool and dry, say, in a basement for instance.
