fatshot $8.99 ..........Still high,
Unless it's a media type package, you won't get much cheaper. iirc, flat rate envelope is $7.50 & box is $8.50.....something like that anyway.
I ship a lot of 2# boxes and cheapest I get is about $9, for someone 'fairly' close. West Coast, CA to WA is about $14 now.
My GW order last week was on that $8.99 shipping to IL. But..........the damn taxes!!! 🤬
