If I pre-enrolled with one provider and then see that a different provider has a cheaper price, can I switch enrollment providers mid-stream?

You are not charged the application fee until you have completed your application in person and can switch enrollment providers until you have completed the enrollment process at an onsite provider location.  Please note you will need to re-enroll with the new provider. If your application is incomplete, your data will be purged after 180 days from the enrollment provider's system.  However, once the in-person process is complete for both new applications and renewals and payment is taken, there are no refunds.
