Do you stock up on accessories when buying a new item that requires them?

Edit Discontinued not discounted.

Sounds smart. I need a new vacuum cleaner belt and it’s possible they have discontinued it because the vacuum is old. That’s unfortunate because it’s a great vacuum. I tried to find a replacement in the same brand, but it won’t be as good. I should have bought a bunch of belts last time.

No. I buy them if and when the need arises.

It’s a smart idea, but no, I don’t

For things I consider “important,” yes.

Only if needed in the near term. I will store them and forget where I put them.
