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.
