I just ordered some parts from Creme de Vape, my order is in Chicago in customs...still.I got one a while back from Provape for around $12, but since it isn't attached I kept forgetting and dropping it on the floor when I took a tank off. Now it's sitting in the can with other accessories. I would like a black one like PV has in stock now, but at $17 for a little more money I could get another 2.5. Doesn't make much sense.
Crème De Vape has their own version which is slightly tapered to mate up with a Kayfun tank. I'm trying to figure out if I can order them from America and ship to someone in the UK. Then I could pick them up when I go over there for a visit. Otherwise the shipping would cost way more than the rings.
Seems like an unnecessary luxury either way. vaping gear is a gadget not a fashion accessory. To me anyway.

But shipping was only $10.95. Royal (Air) Mail, Signature Required, Insured up to $250.00
So, I really didn't think that was too bad.
I figured that shipping from anywhere in the US would be $6.00 minimum anyway, so I decided to go ahead and place the order.
Anyway, just thought I'd mention it to let you know. I thought it would be a lot more than that.
But of course, you be the judge if it's worth it to you.
I'm not thrilled to have paid right at $11.00 for shipping, but I'm down to only needing odds and ends, here and there, so I'd have most likely had to pay shipping if I had ordered from here in the US anyway.
Also, I only ordered some parts. No nic liquid, or anything that wasn't available prior to 8/08/16.
