hi m8
I have contacted ebay to see why this keeps happening, but as usual they are slow to answer in person.
I also sold some R2 bits today and the guy bought two bits no problem, but the third bit he was after said he could not buy it also, so he just said he refreshed the page and it was fine.

if you still want try again, or contact me
