Artist shop & other print to order services

I've been out of the self promo, selling art prints, etc, game for a while - a couple years ago it was really Society6 and Redbubble that ran the game - recently I've uploaded my stuff to INPRNT that offers the artist half of the commissions - which is pretty solid in my book. But I'm wondering where you guys push most of your art - and an average number of sales you make per month?

Also how is your Threadless Artist shop treating you? Mine is pretty desolate - my reasoning is in my opinion, art prints appeal to the masses more so because of the universal appeal of having a wall for artwork vs the varying sizes of people, and seemingly infinite varieties of apparel to print on - that sort of dilutes the value to me, as an individual. If that makes any sense.

That being said - how's your artist shop going? What other outlets do you use to sell prints or art? All feedback and input welcome,

Thanks!
