Are everyone's tanks so full that no one is interested in buying plants? Do we need to actively recruit newbies so we have some empty tanks to fill?

When Amy and I first joined (last October), there was ridiculous competition and numerous bidding wars, and a bag of plants that went for less than $5 was considered a bargain, regardless of what the plant was. But recently, anything that goes for $5 or more is a rarity.
We've been in the club less than a year, so maybe this is part of a cyclical pattern we can't recognize - does this happen every Spring and Summer? Or could this have something to do with the one bag per species rule? (Although that would be counterintuitive, because knowing there will be fewer bags, and knowing they will be more full should lead to higher bids, and more bidders, so that can't be it). The last meeting where I can remember real bidding competition was at Viktor's house. That was 7 months ago (granted, we missed the February and June meetings).
I'm just concerned that people will stop bringing things to the auction if they repeatedly see their cool, interesting, valuable plants receive no bids, or go for only $1. I'm concerned it could hurt the club. Should I be?
