It is so worth it! I agree with the comments above, the journal is fantastic. Also the voucher!
Many nursery's take the voucher, some even offer more than the 25.00 value, depends on the nursery. I used mine at Maryott's and got some fabulous things...for CHEAP!!!! I have recieved a few more catalogs too. I enjoyed my first year so much I went ahead and took out a three year membership. It's really hard to go wrong.
