I've not heard of WOV or used them. One thing I would say is they have a "ECF Registered Supplier" icon on their website, but when you go to the forum suppliers section of the forum (top of the page on the menu bar), they are not listed.
Don't know if it's an oversight or what, but it just seems a little weird to me.
It's a decent price and the website seems legit with their forums and blogs, but who knows. If it were me, I'd pay the extra $3 and buy it from Discount Vapers who I know are legit.
No offense intended to WOV by the way, I am just very careful who I give my credit card details to.
