Holiday Season:
November 1st - January 15th

As the holiday season approaches and Covid-19 continues to shift purchasing patterns from in-store to online, postal delivery may be slower than usual. Such possible delays are outside our control. Team PharmaServe asks that ALL patients place orders well in advance of running out of medication to avoid any additional delays during the holiday season. Please contact us if you have any questions or concerns.
