Good luck to all with this contest.
what retro item would I want for under 100.00? That is a good question since I really have everything I could think of for my collection. Most everything I am missing now are all almost over 100.00. I would guess a few boxes for some of my loose cartridges so I can complete my box collection.
One thing I just missed out on was the Special Edition Fire Emblem 30th Anniversary collection for the Switch. Most of them are on eBay now for around 100.00, some a little more, and some a little less so that is one thing I would also wish for.
