Would you buy Pyrex replacement lids spur of the moment?

I have round Pyrex food storage containers, and one of the tops is lost, and another is cracked. I looked in stores like Walmart, Bed Bath and Beyond, kitchen gadget stores, supermarkets, and nowhere can you buy replacement covers, I had to order them online.

If you walked by a kiosk or a flee market table that sold them, would you be inclined to buy some on the spot? Even if you didn’t need them? To have some extras?

Any chance you currently do need at least one?
