Hey wings02, I think they have done free shipping promotions in the past, but those were special limited time situations. They do charge for shipping now, but $97 is a pretty good deal for that.
I don't own one, but I have spent quite a bit of time with them when I reviewed four of their 2020 models earlier this year. You can check those out here.
I came pretty close to buying an XS for myself, it was my favorite out of their lineup.
The first generation cost $199 to ship. You're lucky. I had two Sondors fat bikes, sold them after I bought nicer bikes and didn't ride them any longer.
