A:AnswerYes, Best Buy does offer international shipping to Spain. However, the availability of international shipping for specific items and the shipping rates may vary depending on the item and your location within Spain.
To determine whether a specific item can be shipped to Spain, you can visit the Best Buy website and add the item to your cart. During the checkout process, you can enter your shipping address to see if international shipping is available and to get an estimated shipping cost.
A:AnswerTLDR: (probably) Yes
I can't confirm. However, I have a European version of the original Switch console and it works fine in the US with a $2 adapter. Most electronics are compatible in this manner, so I'd be willing to bet that it will operate in the usual voltage range.
