Eight Vape is actually a US vendor, not in China, and I bought lots of stuff from them years ago when their prices, sales, S/H, etc. were good. However, they've increased their S/H fees and have fewer sales with decent discounts since then. I also had 2 bad experiences with them...[not getting things I ordered and paid for that were In Stock when I ordered them]. So I've been buying from Chinese vendors [HealthCabin.com, VapeSourcing,com, and SourceMore.com] and the following US vendors instead. VapeSourcing.com even has a US based warehouse they ship from, too, so S/H on items from there is less.
Eliquid.com and Ejuices.com - both are owned by the same company, but their In Stock items are sometimes different, and/or the same items may be available at both, though at different prices, Both frequently have 15%-25% off coupon codes for discounts, too. I've just recently gotten some really good deals on several mods on Eliquid.com, and got Free S/H on my orders. The Adult Signature Required Fee had to be paid for, but the higher actual shipping cost was Free. Most times the coupon codes are shown on their websites, but you won't miss any of them if you sign up for their email newsletters to be notified of new ones.
There are also other reputable US based vendors who are having Sales now for various reasons. WetVapes.com [20% off], and MyVPro.com [50% off going out of business sale] are 2 of them.
If you already like, use, or want to check out any of the Innokin mods, kits, tanks, RTAs, coils, etc... InnokinStore.com is a very good website to go to. Innokin products are manufactured in China and shipped from there to most buyers around the world. However, they ship to US buyers from a US based facility located in Texas. So the S/H is very reasonable and those items arrive quicker, too.
