Were our own shops always visible and had a buy button in shop search? I can't remember to ever have seen mine, but I just accidentally tried to buy from myself which naturally spit out an error message and now I'm confused if it was always like this.

Yup, it was always like this. I've accidentally tried to buy from my own shop several times while questing, you're not alone. :'D

Oh, okay :D Thanks!

No problem! Love your HA, by the way. It looks stellar. ;)

hehehe - thanks! We're a space glam pop band, so I gotta be. You're looking quite good yourself! Can't make out the theme, though.
