Bottom line is that any one can ask any price they want on ebay. If you don't like it don't bid. Doesn't really get any simpler than that.
His name ebay name is joeandme and point of sale is Nevada. I didn't see anyone named control line control line in that link or any reference to $8 needles.
"Reedie", with an "R", not an "N" in the front, is a nickname for a Cox reed-valve engine.And if you buy ten of something for $80, they're costing you $8 apiece.
I see that now. Yes, I am familiar with the term "reedie", but my mind's eye saw it as needles. Brain fart.
It is not just e-bay, besides who would buy use cox when new parts are available?
