One good thing for them to come of it, at least now any potential buyer seeing the listing for the first time, & seeing 140 were sold, may feel more comfortable about paying the price as it 'obviously' must be a good deal for so many others to have bought it (ofc, that's provided they don't look up the sellers sold listings history & thus aren't aware the 140 sold went for 99c each).

If it was an error then it was a big 9k oops in potential lost revenue (approximately, after accounting for FVFs). If however it was an advertising/promo deal, then for a large store/brand it may not have been all that expensive (especially given their actual manufacture/wholesale costs would have been far less than their normal selling price).
