Sorry I am still new not sure if this is the right place to post this. I just won an item (nepenthes) on ebay but the seller don't know where to find heat packs. I am in Boston and we are in our 30's right now during the day and much colder at night. But I live in a condo complex and all the packages stay in our mail room. So do you think it is necessary for the seller to ship his plant to me with a heat pack?
