Found one big name online NY store offering them at 189.99 with free shipping (incremental price of $50.00 over 32GB doubles the capacity.)
I have no association with any of the companies nor Delkin; just a happy user of 32GB Delkin 420x cards from BAA store.

While I make as many purchases as possible from the BAA store, I find this deal too good to pass up....(Hint: BAA store, go negotiate with Delkin to get similar price on 64GB CF).
