You can order direct from them but I have no idea about pricing. Be careful about ordering over the Net because most places tack on a "perishable goods" charge of $15 or $20 to ship chocolate products in dry ice.
But yeah, the Pure De-Lite dark chocolate is 0 net carbs and tastes better than Hershey's Special Dark. Most of the other flavors (mint chocolate, chocolate almond, etc.) are 3 net carbs. I experiment with foods every once in a while and did an unscientific test with the dark chocolate...I ate four bars before going to bed, my
weight loss chart never wavered and I was still in ketosis/lipolysis the next morning (ultra bright pink stick). Since that test, I don't feel guilty at all having one of the dark chocolate bars for dessert each night.
Check in the health and supplements aisle and then dig around for the foods. While looking for Atkins and Pure De-Lite, also check out EAS low carb bars. Some are really good, some are an acquired taste, some are nasty. The Chocolate Brownie and the Cookies and Cream are awesome. Chocolate Peanut Butter is alright...very tasty but kind of chalky. Any fruity stuff like Lemon Cheesecake is downright nasty and leaves a chemical aftertaste.
