I would not pay anything as I have those. Well at least the ones I want anyway. If I had to guess on the high side I would say $50. I have gotten boxes like that from other members for cuttings and or postage $5
I am almost afraid to ask what did you pay?
Do you want some huge plants cheap? If so when I go the the next club auction I can pick you up ONE plant bigger then all of those put together for about $12. Especially crypts which grow like trees in chicago water. I have a red wenditii that takes up a whole 30(the only one i use tap in). It however is staying right where it is.
P.S. your new coffeefolia is dead. It should be deep green
