I definitely agree that the holiday bills rolling in impact the overall flow of sales. And as one of the only ladies here from a female point of view, maybe the Valentines Day (albeit silly unless you're getting your girl a T206) ridiculousness could be a factor? I know it's totally a girly thing to think of but maybe it has something to do with supply and demand?
Also, I try to put up what I'm selling in batches (I also do rare books @BMTbaseballandbooks) and with the USPS uncertainties and changes it's making me less inclined to list items individually outside of a batch instead of all at once. When finishing up my last batch, every day at the post office I heard the workers saying things like "do those new rates apply to this yet?" which was kind of discouraging. Several times I even heard them mumbling about changes that neither I or ebay (at least publicly) were aware of and when those changes were to be implemented. Definitely weirded me out and made me hesitant about what might come next (unless it has to do with the Johnny Cash forever stamp which they knew nothing about). The workers were literally talking about updates to the system whenever I made a visit. Anyways, I'd be more than willing to put up some raw T206s for everyone before I put up my next batch...especially if they're going to be a Valentines present
