yes, you are missing something. go to main page. click on plastic tubing. turn the page once or twice until u see the R-3603 grade lab tubing. its like 3.30 for 1/2" ID, 3/4" OD. its cheaper to get from DDen, but it'll take a bit longer. USplastic has the cheapest prices of the 3, but they ream you on shipping ive heard.
