I know eBay has “eBay envelope” for like certain collectibles but that’s limited by category (that service also has never worked for me), so perhaps this seller just has a custom shipping rule that is that low? But they would lose money on a sale like this. I suppose the hope could be that people buy multiple items at once if they have plenty of (in this case) retro games

$2.95 shipping is plenty for a bubble mailer with a game case in it. Additionally, there’s tons of fraudulent packages right now and the instruction from management is to just deliver it even if you catch it.
Ive never seen a bubble mailer cost less than $5.40 as a seller and that’s with ebays discount, im talking 2 ounces
You could be right. I know delivery better than postage pricing. Seeing $2.95 on a label wouldn’t trigger any red flags to me.
