As you may or may not know, Nintendo does a thing with Mario on what they call Happy Mar10 Day on every March 10, because in March the first 3 letters is Mar, and 10 is the date, so, put them together to get Mar10. During this event, sometimes Nintendo has some Mario games up for sale (digital/physical). You can check out the list of events at this link below. Let me know if you are participating this event at any way.
