Vendor feedback ratings on the main site are only a small piece of the puzzle and are all too often manipulated with bogus shill accounts. If you want to make an informed choice you have to use the forums like your bible before pulling the trigger on an order, the whole feedback rating system is flawed big time imho especially when it is so subjective in its current format. If you have any issues you should contact the vendor first before leaving feedback, that is the only honorable thing to do, I can fully sympathize with vendors who are either held to ransom over threats of a bad review or have bad reviews posted with no effort to resolve issues first. Shipping delays are often out of the vendors hands, to leave bad feedback because of that when you can prove it was shipped on time is just stupid. It maybe a generational thing with many buyers treating this place like fucking eBay.
