We highly recommend having your candy bars shipped in an insulated mailing carton if the weather is warm (above 75 degrees). These are available for purchase for $8.95 each and are directly below the candy bars & wrappers on our order forms. We ship by your choice of USPS Priority Mail (2-3 day business delivery) or USPS Express Mail (1-2 business day delivery). Please make sure that someone will be at your location to accept your package when it arrives. We cannot be responsible for chocolates that arrive melted in shipping. We do not have any control over the handling of your order once it is handed over the carrier. USPS Express Mail delivery is recommended for shipping chocolate from May through October. However, it is quite a bit more expensive than Priority Mail. U.S. Postal Service Priority Mail generally only takes 2-3 days to arrive and is considered a reasonably safe mode of shipping when used with a cooler and ice pack combination for most locations. We ship our wrapped candy bars on ice (we use Ice Wrap™) in an insulated cooler mailing carton. They are safe on ice in our cooler mailing carton for up to 3 days from the time they are shipped. Once your candy bars arrive, they should be removed from the shipping box right away and placed in a cool, dry area until you are ready to use them. We ship our wrapped chocolate candies on Monday, Tuesday or Wednesday only to help insure that your order will not sit in a post office warehouse over a weekend. Please contact us if you have any questions.
