Avoid Peruflora!!!!
I have mixed feelings about this.
I agree that these posts are unfortunate, as they can give the wrong impression, however - also from a vendor's point-of-view - when I ship a plant, I feel it is my responsibility to package it as well as I can to avoid damage.
I certainly wouldn't ship a plant in the winter without heat packs and lots of insulation, as I know that, despite warning labels on the box, the package will be exposed to cold. Protecting the plants from heat in the summer is no different.
That said, I do not ship plants internationally, as that adds additional, major burdens to the packaging needs, and despite your best efforts, they can be undone by the authorities en route, leaving the plants vulnerable to the damage you sought to avoid.
