I am not assuming what you're saying. For any listing, if 300 vs 900 people see the listing, and there is talk about the item creating a buzz, the price will go higher.
re: cods vs combinations, I actually think the CODs record is way better, it is much more Chicago sounding and has a killer ballad flip (the combinations also has a good ballad flip, although not as good). "Coming back to you girl" is awful IMO though. I don't know which one is better in terms of northern soul, but if anyone has a CODs and wants to trade it for my Combinations, I'll do that right away.
