Would you buy warranty for 2 lens cap?

I bought 2 Leica M Lens cap for 2.99 from ebay, soon after they were delivered i received an email asking me to get “warranty” in case the lens cap spoil”.

So being curious i went to the website and get a quote, since they don’t really have lens cap as a category I chose “Other electronics”. Guess what, it will cost me 4.99 to insure my lens capĀ againstĀ damage for one year?? Hahaha I wonder why they even bother to quote me, the website should just tell me that’s its too cheap to insure.
