The earliest copies of the Blu-ray/DVD were sold with limited edition postcards. These are now very, very rare. The Blu-ray/DVD must have the sticker on the box if it contains a postcard. No sticker means no postcard inside.
Just like season 4 boxset, normal non-lenticular slipcover for the Blu-ray.

If you just have a ton of money burning in your wallet, Cryptozoic has released some very expensive collector's cards. You can find them listed on places like ebay for hundreds, sometimes thousands, of dollars. Only Season 1 was released as a card set. Cryptozoic does not have the license to release any more seasons.
The 2014 Cryptozoic Once Upon a Time Season 1 base set has 45 cards covering the first 22 episodes of the series. Each factory set includes the same 45 card base set, plus a handful of special additional cards. Additional cards:
Autograph cards - cards autographed by the actors from the show.
Wardrobe cards - swatches of costumes from the show.
Sketch cards - sketches of the characters by famous artists.
Each 45-card factory set contains 2 wardrobe cards, 1 autograph card, and 1 random special card (autograph or wardrobe).
