Poor quality control. Poor customer support. I placed orders for several samples from LuLu (both in Shopify via the app and through xpress.lulu.com). The gloss cover paperback was fine, but the matte covers on three different paperbacks were badly curled. I also contacted support about the customized packing slip: LuLu acknowledged that there was an issue and said its developers were investigating, but it's been three weeks now and I still haven't heard back... It's a pity, because done properly I think this service would be a tremendous success (many small publishers would welcome the ability to have a third party process single book orders for them from their own websites) — but there is no way I could sell such a shoddy product to customers.

I use Lulu xPress for about two years now. It worked well until several months ago and it became a disaster. Apparently there is 0 quality assurance made at the printing facilities. I have numerous copies of my book delivered with pages empty of content. The support is always helpful and sends a replacement, but in last several weeks I had several clients who received faulty product even on second and THIRD attempt. Unfortunately it damages my relationship, since I really look unprofessional when customer receives a faulty product, then the replacement arrives faulty again and the next one again. It also affects my income since I have to refund such customers. I asked for clarifications when such issues can be fixed but didn't receive concrete answers. If you have an alternative consider avoiding Lulu.

Update: I really wanted to come back and change my original review saying things were resolved, but I can't. After multiple attempts, I finally got a human on the phone, who I thought was helpful. They did enable my product in my store so that customers could order, which they did, however, it has been 20 days now and the order has not even gone to production because the original issue was not fixed. I am stuck with $400 in sales, no product, angry customers, and still, no answer when (or if) they will get their product at the height of the holiday season. If I could give zero stars I would since they have done nothing to assist nor can I get any product. I made a calendar for my Shopify store, it shows up in my store but you can't order it, I keep getting an error message when attempting to place an order. I have contacted their customer service, no response. I contacted Shopify, they confirmed it was not on their end and contacted Lulu xPress's customer service copying me on the email and I did get an email back several days later. I sent screenshots as requested and since then nothing. I have tried for 10-days to resolve this and nothing. I will move on to another app and start over.
