Market always tells me unique tablets are ":No longer for sale"

I've tried buying multiple different unique tablets from the instant buy market, and in every case, I get the message "The item is no longer for sale", despite this not being true. It happens both in-game and on the website.

The first attempt


Two minutes later


If there is a workaround, I'd love to know it.

ofc those are instantly bought out by bots.. way too cheap

pay full prize and you will get your thing
