This was a weird one. I only saw 4 sales on my daily report for Saturday, the 8th. Last night the 8th dissapeared completely, (not in monthly or daily report). This morning June 8th is back, with several more sales reported as well.
Yeah it seems every few months BN doesn't report accurately for a few days. I'm as anal as the next guy with checking sales but don't let it bother you. They correct it within a reasonable amount of time I've found so give it a few days and it should be corrected and everything back to normal hopefully.
