Phals certainly are available everywhere, but they're not cheap unless you can buy them after they're finished blooming. I used to buy them for gifts at Trader Joe's, mini-Phals were $6.99 each but now? $10.99 last time I saw them. The full-size ones are $25 or more, and TJ's still has the most reasonable prices on them.
Back to watching the "death racks" at Lowe's and buying the spent ones . . .
