Khwarunee has a triple white, and a double yellow(that has pink stripes) for USD $27 each. Her plants are big and strong, a good value. She was almost wiped out by the floods last year, but she's still in business and struggling to make a comeback. Here's a link---

$12 plant, $15 packing and shipping. Don't get all bent out of shape about the shipping. Thailand is a long way away.
Mr Ko, adenium_ko, has hunderds of offers for good seeds. I have always had great germination, and now it's spring time, best time of the year to start seeds, no? His shipping is $4, and you can put everything together for that one fee. Hmm, I'm talking myself into buying more seeds!! Some of his mixes are 100 seeds for 99 cents. Ha, if you have a vegetable garden, put in a row of Adeniums, 500 sees for $9, not bad! hahaha
