I ordered from RedBubble a number of times and only had one bad experience.
I ordered a T-shirt that, at first, I thought was perfect. But when I received it, my graphics designer eye caught something on the right side. Apparently, when printed on the fabric, the printer forgot about half a centimeter, cutting the motif/drawing a bit short. I sent a picture, along with my finger on the marked space, asking for one where the printer didn't skip on the job, but it turned out that they ALL had this default.
They offered to give me my money back, but the t-shirt is so comfortable that I decided to keep it anyway. Still, they were very open with me.
Even when I forget to include coupons and promo-codes in the right space, they are always open to include it if you ask them too -- as long as it's right after you do your order, if not at the same time.
I would have given them 4.5 if I could (there is no such thing as perfection in this world in my book). The only thing is that I would love their search engine to be a tad more efficient; the last search results don't always match your query, and the simplest things don't always show up.

The Sabers I received were in perfect order. I received them faster than expected, althought received a phone call the same morning, telling me to prepare cash for the TPS and TVQ (federal and provincial sales taxes). I scrambled to get the amount necessary -- in this day and age, who has more than 50$ in cash at home. When the delivery man arrived, he said it wasn't necessary to have the cash, that a check or credit card would have suffised.
As for the Sabers themselves, the learning curbe for the Diamond Software is incredibly steep and stressfull. Barely "user friendly". Fortunately, the Ultrasabers Customer Service staff is more than able to help. I only regret they only communicate through e-mail and that the chat window on their web-site is as easy to catch than a mosquito inside a school auditorium.
For the paying customers, I would suggest a reserved hotline, even for a limited time (the first three months), to help them get them through the Sabers functionalities or warranty. One would enter the order number as a PIN number, valid for N-months following the purchase. Considering the costs of the Sabers (especially the Diamond), that would be a grace instead of having to run through their forum.
