Switch Buyer Scammer

I'm concerned because the year JUST started and this account with no history made me an offer on my Nintendo switch. It's animal crossing edition and only a few months old (I bought in October played a lot for about a month but finished the only game I was interested in) this account offered $100. I countered the offer and They said after fees and shipping they would be able to get a brand new one from the store for cheaper and would appreciate me considering their offer as it's in their budget...but my shipping is $8.49 and the fees are around $20 I believe so this is still well under what a REGULAR switch lite new is currently $180.... The animal crossing edition is a lot more (mine doesn't come with the game installed but it's still a special edition so I think my price is more than fair considering it's condition). They also sent a long message about how it's for their daughter because her old one keeps overheating....should I be concerned I'm being scammed? Or do you think they're mistaken?
