I'll plan on mailing stuff to myself, probably to the clinic, about 2 weeks early. Hopefully that'll allow for winter weather.
Just a warning that the USPS has a whole host of strange and often illogical restrictions on what can be mailed. Make sure you review the restrictions before trying to ship via them and/or be very careful how you answer any questions from the mail clerk.
OTOH, that may just be a myth...
