I bought a large lot of these discs and years later realized the seller made a terrible mistake. Instead of sending me complete sets, he sent me three boxes of the same discs. Whoever bought the other lot got three sets of 1-40 So I need discs 1-40 I have three sets of discs 40-163 I would like to do a straight trade of 40 discs for 40 discs, or 40-163 for discs 1-40 and some other trade. Cheers.
