One perk to being a My Nintendo member is that you gain access to the ability to purchase the novelty NES and/or SNES controllers that Nintendo itself has designed for use on the Switch. These wireless renditions of the classic controllers are currently back up on the European My Nintendo Store, with the NES variant being marked down by half-off, bringing the price down to £24.99. SNES fans get to enjoy their controller of choice for £26.99.
Both of these controllers have mainly been designed for use with the NES and SNES game selection for the Switch Online service. These games are accessible by any Switch Online subscriber for free.
