I have been buying my e-liquid off of eBay for awhile now because its VERY cheap (Were talking around $10 for 90ml) and good if you find the right sellers. eBay has a policy where they don't sell any nicotine and I like nicotine in my e-liquid so what i've been doing is mixing different flavored e-liquid with my ebay liquid to give it nicotine, but it mixes the flavor and I don't like that. So on the website where I buy my vapes I found unflavored nicotine e-liquid base. It is 24mg per mil, and its 125mil in the bottle. If I buy this can I mix a little in with my other ejuice and vape it?
