I am very happy to buy from Amazon and Digikey even if
sometimes they are
a little more expensive. I want them to be around for the long term, so I
support them as much as possible. Their range is amazing.

Ours comes from Mouser, between two part #s they have over 7,000
74LS04s in DIP packaging in stock. Didn't check ACT, HCT, or ALS. I

think we've had a 7400 series part that we couldn't just order off Mouser
in recent history, and we're usually buying QTY 100.
You can also buy parts direct from TI, for example they currently show
around around 3000 SN74LS04N parts in stock.
https://www.ti.com/product/SN74LS04/part-details/SN74LS04N
The prices for that part match the current Mouser prices of $0.674
each, or $0.519 each if you buy at least 4 tubes of 25 parts.
I've bought some tubes of 74LS parts direct from TI in the last year.
