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.

Using the holiday sale offer saved a nice amount on my holiday cards offer. Their quality was good, colours were vibrant and the stock was of good quality. Most importantly: delivery wa on time (2 days later) Like every year I was late with my order, so there wern't a lot of options to get my cards done in time. When i saw the offer from Overnight prints i took it, and looking back im glad i did.

MOO is the best! I started working from home crafting dog products and I need some professional business cards and accessories. My neighbor is a freelancer and he recommended Moo. Since I am just starting out I went for their most simple and less expensive option, but I will upgrade my business cards in the next couple of months.

I have ordered the photobooks from Tiny Prints several times, and im really happy with their product quality. Their online software is easy and fun to use and the templates are wonderful. Qality of the books is excellent and shipping quite fast.
The only negative thing i can say about Tiny Prints is that it sometimes hard to get a hold of customer service.

When you first get a glimpse of their website you don't expect very much. Let's face it, their website looks pretty outdated!
However, and this is a big however, the printing quality speaks for itself. I usually use them for business cards and flyers but I also had to get some calendars and they look pretty good, considering I used my own photos and they were not very good looking.
One huge downside is the fact they don't offer a lot of customization features which is a shame, considering they deliver high quality printing at super affordable prices. Give them a try, you won't be disappointed.
