It's cheaper to just cut it with glycerin, DIY style.
Example: Let's say you like the cappucino as your favorite and you usually vape 16mG....
BUY the 50mL bottle of Cappucino in 24mG then cut it down to 16mG by simply adding 25mL of clycerin (in a bigger bottle of course).
HUMCO glycerin is available at any WalMart or well stocked drug store and it is VERY CHEAP (ask pharmacist in either case to tell you where it is on the shelf). I personally don't like this clycerin, which I believe is actually synthetic.
I bought 2 small bottles of WILTON glycerin on eBay...which i suspect is better that HUMCO. I'll be trying it soon. Apparently, bakers & chefs commonly use WILTON glycerin for cake icing/frosting arrangements.
Two other good brands of glycerin are LORANN....as well as the "NOW" brand which is actually VEGETABLE GLYCERIN available at most HEALTH FOOD STORES. It is my understanding that it's not very expensive for a good sized bottle.
IF you try to mix glycerin fresh out of the fridge, some brands of it can be rather thick. Let it sit outside the fridge for awhile or heat it SLIGHTLY in the microwave before mixing. Be sure to SHAKE WELL. Best bet is to refrigerate all your vaping juices.
If you plan to use it with an epipe, BE SURE to leave the pipe in a DRAINING POSITION when you're not actually vaping with it! It DOES THICKEN your vaping juice and it also cloggs more easily than common PG based vaping juice.
ADDITIONAL NEW NOTES:
As mentioned before, I have determined that I do not like the Humco (synthetic) glycerin. Wilton is definitely better synthetic glycerin than the Humco. It is easily found on eBay.
Today I compared Wilton (synthetic) glycerin with the HERITAGE brand of VEGETABLE GLYCERIN which I got at a local health food store. I used each type to cut/thin some 16mG cappucino by just 25%....thus, making it 12mG. I vaped from TWO DSE601 EPIPES...SIDE-BY-SIDE.
Both vape nicely, but the Wilton is more likely to CLOGG the DSE601. The Wilton also did not preserve the original Cappucino flavor as well as the HERITAGE VG did.
So there you have it. In my side-by-side comparison, the HERITAGE brand of VEGETABLE GLYCERIN works better than the Wilton SYNTHETIC glycerin. That tells me that the HERITAGE VG probably also works better than that synthetic HUMCO stuff. I hope some folks find this helpful.
It seems likely to me that VEGETABLE GLYCERIN generally works better than SYNTHETIC GLYCERIN.
The HERITAGE VG was only about $5 for a 4 Oz/120mL bottle....yet I paid about the same price for just ONE 2 Oz/59mL bottle of the Wilton glycerin....which I'm neary certain is synthetic glycerin. Personally, I'll go with the HERITAGE VG. I've also heard that the "NOW" brand of VG is also very good. It is also sold at health food stores. I dumped my HUMCO glycerin (from WalMart) right down the toilet LOL
