Buyers don't have to rate, I had a few not rate me.
Me too.
The only time I didn't rate was when a seller waited until the last day to ship, never ever responded to my messages after payment ( she answered me in 5 minutes BEFORE payment), she just threw an expensive item in a large brown envelope with no padding or anything. It was completely smashed but it was in good condition so I didn't leave bad feedback. If she had just let me know what was going on I would've been OK but just ignoring me after payment was rude. I didn't even message her until day 4.
