Can you buy the care separately?

I bought mine from Amazon and I was looking see if the care+ can be purchased separately. I'm returning the size 9 tomorrow and replacing with a size 8 since I found out that the 9 is too large compared to when I used the sizing kit. Either way, can you get it separately or if someone can tag the company spokesperson for ringconn that's in this forum? (idk how to do that)
