Collector had a good eye for vacuums. Wonder how much this flipper paid for the lot to think it's worth $2,500.
$2,500 divided by +/- "50" works out to $50 a vacuum (less if there's more than 50) which isn't really that bad considering.
A lot of rare vacuums in there in great shape that you wouldn't find for $50 anywhere else, so that much is going for it. Just a large chunk of cash to spend at once unless you know you can make the money back.
