I forgot to mention I tip the QSL managers both US and DX.

QSL Managers and DXpeditions can use a little more than postage for printing
up cards
And some have a slush fund to place postage on SAE or QSLs they receive with
no or insufficient postage.

Some QSL managers save the QSL cards with no return postage and periodically
dump them into the Bureau, can take a year or two to get back. So include
proper return postage if you don't want to wait for the burro.

I also tip the rare USA states to help with postage and QSL printing costs

What is a rare USA State ?
See URL:

Example Wyoming has 1614 total hams -- subtract out the inactive and
non-HFers and u have very few WY on the HF bands.

I also send the DXpeditions a fiver -- they can spend lots of money on their
operations.

Example: 3D2, CONWAY REEF DXpedition ($45,000)

Many DXpeditions are much more than that !
