WTB ocellatus or brevis group

[SpartyTim]

Have a couple tanks cycled and loaded up with shells... now all I need are a couple of groups of shellies. All I can find locally are multis, but kinda had my heart set on two species tanks of ocellatus and brevis.  I could order some, but thought I would try here first.  I am outside of Lansing (Williamston) and my teaching and parenting schedule will not allow me to drive too far... but I do get down to the northern suburbs of Detroit once or twice a week. (not familiar with the stores down there)

Thanks for any help, Tim
