Bert (Bleek) at Touch of Nature has a lily sale going on now, and he's always open to larger quantity purchases, usually at a nice discount. Some of us in the mid-Atlantic forum are putting together a group buy (for distribution at the spring swap) using ToN and ADR as our sources. ADR is a wholesaler, but if you ask nicely they'll work with you if you're looking for a source for group buys or garden club co-ops. I've also had nice bulbs from Sunshine.
And although I've never ordered from them, I hear the really top notch bulbs are those from B&D lilies -- and I think you're in their "nearby cheaper shipping area." They do have discounts listed for 3 or 6 of a kind, and I'll bet they'd work with you if you wanted 25 or 50 bulbs, too.
No, I was inquiring about a good source for high volume/ great discount for volume Star gazer lilies. van Engelen was "sold out" of everything I was interested in. I think you're right, that is their way of saying "not now"!
