89.8% feedback rating?!?!?! YIKES!!!!
For the record, I will almost never buy from a seller with less than 98% feedback.
If they only have a few feedbacks, then I'll read them and decide, but once you get to about 1,000, you better be above 98% or you have some serious problems.
I have bought hundreds of things on ebay. I have been screwed over twice, and those were both big sellers with marginal (95% ish) feedback.
