Heartland has always been primarily business-to-business. My theory as to the reason they sell nic cheaper than anyone else is for the same reason a local greenhouse in my area sells a professional potting mix at break-even price to the public (they use this potting mix to grow their own seedlings). In order for them to get the potting mix at a good price, they have to buy X pallets per quarter. To ensure they maintain that ordering level, they sell it at a break-even price to the consumer.
Maybe heartland is doing the same. Heartland sells nic to other businesses as well as makes juices by contract under your own brand name. Maybe they sell nic at a break-even price to consumer (or small profit margin) to help maintain a certain ordering level that gets them a better price with their nic supplier.
Hard to say.
Others sell nic higher because they have to since they buy a lot less. Perhaps they are retail only or a majority of their business. It's also possibly they are buying from domestic suppliers, like heartland and others.
Again, hard to say.
Before I started DIY, I'd been vaping heartland's house juices for may years. I'm not dead or sick...yet.
