to my knowledge, I thought it was something like if its $0.95 it means it's about to go on clearance, $0.97 means they're about to run out of stock, $0.99 means they have a lot in stock or it just went on sale, and $0.98 means they have a lot on the sale floor but none in the warehouse or whatever. It was something like that, I think I read it in an eBook somewhere. Don't take my word on it though, I just remember it was something like that.
