Because it is a highly perishable food item, we do not accept returns. If you choose overnight shipping, we absolutely guarantee that the product will arrive frozen. I’ve even tested sending it to my home in San Diego with no dry ice and it arrived fine. For 2 day shipping, we do not guarantee it, though we’ve only had two complaints—both from AZ and Nevada in 110 degree weather. 2 day shipping is fine as long as you are available to pick up the item and it doesn’t sit on a front porch.
