If you have friends or family members that appreciate abstract art, you might think that purchasing original artwork gifts for them might be well beyond your budget. Tthat might well be true, for famous, professional artists. However, many independents sell their art on print on demand (PoD) sites, and several online artist communities also sell prints of their members work submitted to them.
Of course you will not be getting a unique piece of art, the images remain to be sold on the site. However, there is so much variety available, that it is highly unlikely that two people who know each other would have the same object.
