Been there and almost lost my shirt.

Been there done that, got the tee shirt. 

I'm also gathering that there aren't really any tax benefits with me using the LLC vs. personal financial reporting either.Is my only benefit to the LLC the ability to make polo shirts with cool logos?? 

Preferably with a company you've worked with before and would confidently give a stamp of approval to.

IN most states plumbing fixtures etc are stamped state approved from shower inserts to all other things.. 

The seller paid all the transfer taxes and doc stamps. 

Yes a hand written letter and envelope and live stamp is much more likely to be opened and read.

If you're a store that sells shoes, you wouldn't sell to a customer who's only interested in buying shirts.

That's the approval stamp you need for this kind of business.  

Other than REI, kind of bonus missions: I want to make my dropshipping store profitable, potentially start a youtube channel, and launch an NFT collection along with these anime shirts I designed myself.
