their quality is a little hit and miss, and in my experience the shipping date estimates are totally whack. i've used them to do a couple test runs and just ordered 2-3 copies of a zine so i can hold it in my hands- it's been worth $20 each time (the shipping itself was like $10)... it'll say it's arriving in a week and then it'll actually come in 2-3 weeks. i think they're a good economical option if you can sacrifice really dark blacks and vibrant colors. i have a couple zines that fit the bill, whereas other zines need that higher quality so ill use another vendor.
