Due to new dimensional shipping rates for FedEx/UPS this box set now ships at 28 pounds. Shame on FedEx! So we have flat rated the shipping on this item. If you live out West and need quantity of these please call in and we can work out a better shipping rate.

Styroffoam box for USPS Large Priority Box
This product was exactly what I needed to be able to lower shipping costs and use the flat rate USPS box for my small business. Very few places had something like this so I am thankful!

Does as described
The cooler fits snugly into the large flat rate shipping boxes. Eight regular sized cans fit nicely with a few ice packs able to fit as well.

Excellent product
This is perfect for shipping USPS Priority. I was getting some boxes crushed and this is great for adding rigidity as well as temperature protection.

This is a great idea
I ship items that need to stay cool. Finding styrofoam coolers to fit a shipping box can be either a hassle or very expensive. This item is great and an awesome idea. Thanks for the great product.
