GameCube games coming exclusively to the Switch 2's exclusive online library is one of the best features of the new console. To make those membership costs just that little bit easier, UK retailer ShopTo has NSO at 35% off right now. As you get your Nintendo Switch 2 pre-orders in, this is an absolute bonus bargain to consider.While some Nintendo Classics catalogues are unlocked with the base online subscription, you'll also need the Expansion Pack to play GameCube titles on Nintendo Switch 2. What's more, while you can subscribe to a monthly model for just Nintendo Switch Online, the Expansion Pack is only available on the 12-month plan, so make a note when purchasing.Nintendo Switch Online 12 Month + Expansion Pack 365 Days Membership Download (UK - EU)Nintendo Switch Online 12 Month Family Membership + Expansion Pack 365 Days Download (UK - EU)Currently, the individual versions of these combined 12-month subscriptions cost either 34.99 on the Nintendo eShop or 39.99 at retailers like ShopTo. But now, it seems like ShopTo are keen to get on the Switch 2 hype by slashing 14.14 off the individual plan and 15.14 off the family plans respectively.So, if you're the only Nintendo Switch players in your household, you can buy the individual Online + Expansion Pack plan for 25.85 or the Family Membership for 44.85. Overall, the family version is fantastic value as you can have up to eight Nintendo Accounts under a Family Group sharing the same membership, and you don't have to be in the same household either. Under ShopTo's new price, that's as low as 5.60 per person getting to enjoy Nintendo Switch Online and the entire Expansion Pack's catalogue of gamesincluding GameCube gems Pokemon XD: Gale of Darkness, Soulcalibur 2, and The Legend of Zelda: The Wind Waker for a whole year. If you're like me, though, and have already have a basic Nintendo Switch Online membership active until next year, the only way to upgrade is through Nintendo themselveseither on their website or the eShopwithout a direct discount from retailers like ShopTo.

Buy entering the code "NINTENDODIGITAL10" at checkout, you'll get 10% off on 15, 25, 50, 75, and 100 amounts of eShop creditsaving you as much as 10. In the case of upgrading your 12-month Nintendo Switch Online membership, the cost of which varies depending on how much is left, you can buy the closest amount you need or a larger amount at a bigger discount, and use any extra credit you have on digital games or save it to put toward your subscription next year.Ben Williams IGN freelance contributor with over 10 years of experience covering gaming, tech, film, TV, and anime.
