Nothing but positive! Great turn around times (cards were delivered much faster then expected) Amazing quality of both paper and print (super crispy colors) and the best customer service I've experienced so far.

Inkgarden rules! I'm a sucker for personalized plates and I will use any excuse to order some; my mother's wedding, Christmas season or a new neighbor. They're not super sturdy but they hold on pretty well. I started by ordering some of the designs they feature but soon started making my own. This spring I had to order some personalized hoodies for a marathon so it was obvious I would use InkGarden. The print was flawless and everyone loved them! Have to agree with Aurora Martin, if you don’t use a modern camera the photo won’t print out very good.

Lovely designs but service is slipping and quality dropping when it used to be excellent. Feedback on their site is completely fake (they will only post positive reviews) Been using them for over a decade but my last order was disappointing: send them a perfect high-res image but the print was blurry and showed a blue-ish hue all over. They are reprinting, but it will be to late by the time they arrive.

Have used Cafepress many times, and have absolutely nothing but praise for them. I have recently ordered t-shirts in the wrong size, and also got a mug with a hairline crack along the bottom, causing it to leak droplets of water, but within 30 mins of emailing, I received a response.
They even sent out a replacement mug and told me to the keep the old one, and the same for one of the t-shirts I had bought - that's $25 Dollars and a lot of hassle they saved me, even-though i would have happily returned it.
Best service, i definitely recommend!

Snapfish is useless: I ordered graduation invites from their website. A few minutes after i placed the order i realized there was a spelling error, so i tried to contact Snapfish about it. Their Live chat was totally useless, their phone support seems to be outsourced to some third world country. It took me over an hour to finally speak to someone who promised me they would correct the spelling error.
The cards just arrived at my house, and guess what: They did not correct the spelling error! Totally useless!!
