Moo literally blew my expectations! I was on a tight budget and designed my own cards. I chose the cheapest paper and the cheapest shipping.
The cards arrived quickly and the quality is exceptional! The paper stock is thick and feels nice to the touch.
The quality of the cards can't be faulted, and virtually everyone I've given one to is impressed and wants to know where I got them done.
I will definitely use MOO again and will recommend them to all my friends.

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.

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.

Tiny Prints did not deliver my order by the delivery date, even though I paid for super rush delivery. The did not contact me to say anything was holding up my order. The auto message when you call even said they weren't experiencing delays and all orders were being sent on time. Two different Tiny Print reps aid I would get the order the following day. When I called again to question that, because it was the night before the new delivery date and they still hasn't printed yet, they admitted after some questioning that I would not receive the order the next day. I wasted hours creating the invitation on Tiny Prints and now need to start over with someone else because Tiny Prints has false advertising, poor customer service, and claim copyright issues for not sending me the file to go elsewhere.

I placed several orders with Vistaprint before, and was a satisfied customer until recently. I needed Christmas cards quickly so i paid extra for rush delivery (which takes 3 days). Now we are 15 days later and i still didn't receive the cards that i needed urgently. There is no phone number to contact them, only an Email address where you have to wait for days to get a reply. Finally their reply was unsatisfactory and i still have nothing. They do make you pay upfront, but no delivery and no customer support. Vista print: never again for me!
