Today I am giving a thumbs-up to Art.com, from which I've purchased a few things lately, including this terrific print of Kings Cross station in London, which is where Iain and I met in person for the first time.
I've just had the best luck with Art.com: The quality of the products is great, their shipping time is fast, and they have frequent sales. I can't vouch for their customer service—but only because their service has been so splendid that I haven't had to use it!
I've never used their "print your own photo" service, but I have received a gift from Deeks of an image he created for me (which is just as AMAZING as you would imagine), and the quality was just as good as the stuff I've ordered from the available images on their site.
Anyway! Give us your thumbs-up or thumbs-down in comments!
Just to be abundantly clear, I am not affiliated in any way with Art.com, nor am I receiving any form of payment for recommending them. It's just a thing I've personally found super useful and am happy to recommend.
