Travwell review for Lulu Direct

The app is very glitchy and there are major issues with their fulfillment and printing of the books. Their site has a production time of 3-5 business days which is false advertising. When emailing them about how it is taking much longer, now on 12 business days they respond saying that they're aware of it and that I should tell customers that it is a custom printing job for each and every book and that should keep them happy. This is before the shipping even occurs. I'm only in the stage of printing out proofs and am realizing I likely will not be able to use this for print on demand and dropshipping directly to customers due to the insanely long print time. This is not a sustainable model for print on demand and more so a better model for printing in bulk and holding inventory.
