I think it is more taste and preference over anything else. Yes, canning jars are less expensive, but then you have the 2 piece lid to deal with on some of them. You also have to decide what kind of customers you are targeting. If you live in a rural area, and those are your customers, then canning jars may work. If it an upscale look you are going for, some balmorals may be what you need. Search the web for candle companies, decide who your customers are, and pick out a range of jars that will work for you. Personally, I love apothocaries. I use the 10 oz and 16 oz and find them very versatile. Customers love them because of the way I decorate them. I also sell 8 oz melts in jelly jars with daisy lids. I sell candle warmers for these (usually 2 sales at once). The melts are cheaper because they are less wax, no wick and less work overall. People like choices, but you are the ultimate decision maker - you are the one that has to make them and sell them. You will never sell one thing that everyone likes. That's what makes this business so challenging and rewarding, too. Hope this helped!
