Chocolate Storage for Home Based Business

Hi allIve just found this site and would appreciate any replies. Im starting a small online gift bag company and would like to offer chocolate bars and truffles as well.The suppliers have told me that they have a long shelf life but Im wondering about cost effective home storage. I know they should be stored in a cool dry place (cupboards away from heat and sunlight) but wonder if anyone knows of any type of storage or insulation boxes that might help bring down the temperature even more.I'm from the UK and am also looking for anyone who supplies their own products.Thanks
