Slow Sales past 2 weeks ~ no drop in sales rank

Our website is performing well enough, and our eBay, so I know it’s not, “the economy”. But – our Amazon sales have halved or a little bit more. No drop in product ranking either, in fact 2 of our SKUs went up over 50 to 100 places in product ranking for the niche we’re in. I’m wondering if anyone else has been experiencing sluggish sales lately?

For an idea of whats going on, we average at 22 to 26 sales per day normally. Lately, it’s been at around 8 to 15 sales per day, averaging at the lower end.
