I've purchased plenty of art over the past couple years, mostly original paintings with a few prints. Very few of those came from galleries and when I walked in the galleries, I already knew what I wanted to buy.

Etsy and reddit are easy ways to find rather good art for what I can tell is a consistent price based on the size of the piece.

The only time I 'browse' art offline is during special events, which have all been wander from house to house or small art studio to studio. I love the experience, it's much more personal as you know the artist will be there and you can discuss the piece with them.
