Reply To: Can you request an online purchase for delivery on shabbos??

R’ Eliezer, see מנחת יצחק ח’ ו’ סי’ י”ח for a discussion of this issue, with many poskim mentioned (including the חו”י and מה’ גרשון mentioned by חת”ס), and his conclusion that guaranteed Shabbos delivery would only be muttar in case of great need.
