Signed copies are sold out on official channels.
You probably missed the window. Julia Jacklin’s signed Pre Pleasure vinyl was a limited pre-order item on her official webstore and Bandcamp. Those sold out quickly after the album’s release in 2022.
Your only option now is the secondary market — Discogs, eBay, or fan forums. But be careful: prices are inflated and fakes exist. If you want it brand new with a genuine signature, you’re out of luck unless she does another signed run (which is unlikely for a two-year-old album).
Check her official site and socials for any surprise restocks, but I wouldn’t hold my breath. The resale market is where this hunt ends.
