Planning a gathering ^____^

I need the following in bulk, stat:

3 cases of diapers (important: adult size)
12 sippy cups
Jammies (again, adult size)
Lots and lots of chlorophyll tablets

I need this as cheaply as possible.  I've been looking around at the medical supply places, but they either do not sell direct to the public, or require doctor approval.  I hold these events often enough that wholesale prices are preferred.
