Whilst searching the web for the best prices regarding retainers, I recently read in one of your posts that you quoted £350 for 3 sets of Vivera retainers. I’ve had Invisalign and now use Vivera retainers. What is problematic is that the dentist who is currently providing me treatment with is charging me £495 for a set of three. I am finding money extremely tight at the moment and was hoping of being able to get a cheaper option. Do you happen to know if there is any way I can order them through you instead? Would I need to change providers and do you know how I would go about that?
