If you wanted to get a Ruyan bling you can get the atomiser and LED cap from Wayne direct for $31 USD including UK postage -
heaven_gifts@yahoo.com.cn I don't know how much he charges for cartridges.
You would also need a charger $12.58 (the ones that come with the bling kits aren't great) and
batteries $4.32 - DealExtreme: $12.58 Ultra Fire 10440 14500 Ac Charger
DealExtreme: $4.32 Ultra Fire 10440 3.6V 500mAh 2Pack
So apart from cartridges you could have a decent bling setup including postage for $47.90/£26.06. You might also want to get extra batteries though.
My bling gives good vapour and tastes great with Janty and diy
juice, I don't like the Ruyan cartridge taste. It's great value for money in my opinion but it is chunkier than an ecig and is covered with Ruyan advertising (although it's in Chinese and looks a bit arty).
