I think it's definatly worth only shopping
with 100% pos. feedback sellers & shops with lots of transactions.
I don't mind 99.8 or so, specially if they've sold large numbers, bound to have had one get lost or just an awkward buyer.
If a seller was going to fiddle feedback they'd most likely give themselves 100.
I gave neutral feedback to a seller about a month ago (Gold Star badges - absolute crap), he did give a full refund so gave neutral, hasn't shown up on his feedback yet though
