I used Print Place only once and was satisfied with their service. My business cards looked very professional and they even spotted a typo which they corrected for me. After reading some online reviews I decided to give them a go and I'll use them for my future projects. Very satisfied, professional service.

Inkgarden offers the most flexibility with their design tools. You can actually save your design to complete it later, and their tools allow you to exactly position where the design is located on the product that you create. Adding text is easy, you can use multiple designs, choose if you want to use single or double sided, etc, etc.
Product quality was satisfying, and customer service was helpful.
I will definately use them again.

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.

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.
