Congrats on taking that first step to put your stamp on this community!

On the invoice, I stamped in big red letters the word "Paid" indicating that I considered the commission paid at that time. 

As long as there is no consideration, they should not have to pay doc stamps paid.  

I've used him one before for an LLC but realize there's a lot of boilerplate and window dressing in that cost (fancy certificates, embossed stamp, etc.).   

Florida Documentary Stamp Tax (doc stamps) on the amount of your final bid.

May as well go all the way and ask seller to pay doc stamps on the deed and owner's title policy too because you may have been asleep at the wheel seller.I'm assuming this is a for sale by owner correct?

There may be doc stamps tax too because the property is encumbered.

No money crypto, baseball cards, stamps, coins, skateboards, bikes. 

, If you go through USPS do you have to stamp or address every piece manually ?.  

Michael Roberts I use the same calculator - depending on the state your acquisition costs are higher as your buying the property so you have higher recording costs and County stamps etc they charge you for.
