Do Nzxt Aer RGB 2 Ever Go on Sale?

Does the individual product ever go on sale in some stores, or I'd have to rely on store-wide/eBay sales to catch the discount?

In fact, do any eBay stores even stock these fans? edit: I found Computer Alliance has these, but only 1 in stock.

Camelcamelcamel Aus doesn't have any price history data so I can't see if there's been any drops in price and if so, when.
