I've been a customer there for at least 12 years now. I've had maybe half a dozen issues over all that time, it's rare. Every seller I've worked with have resolved those issues no sweat. I use the Box feature almost exclusively now. I've rarely had issues with card condition. At 18 cents for the vast majority of commons it's not a big deal if a few are beat up, I'll still binder them and upgrade them the next order.
It is worth spending the time to try and source from as few sellers as possible to help save on shipping even to Box.
