I like Bay Photo and WHCC, while NYT loves Nation's
I’ve been very happy with the work and the prices from Canvas discount. Thanks for chiming in.
Several years ago, Consumer Reports selected CVS and Walgreens as there best photo printing places. I find them very convenient (some 24x7) and willing to reprint if any issues. For canvas, I have used for a few 30x40" prints for like $35 https://www.canvasdiscount.com/ and they always have a sale.
I've used Printque (used to be Adorama Prints) for a long time when someone requests a print of my photo on social media. For my house I actually use Canvaspop a lot because I find canvas photos somehow suit my small living space very well (and let's face it, canvas covers up a wide variety of imperfections, plus you just dust it). I just printed a sunrise 48x32 on canvas and I was terrified, but it looks marvelous above my desk!
