Help!

My wife keeps losing the soft ear tips that fall off of her Apple in-ear headphones. And when that happens, she dragoons me to assist her in finding them. We are not always successful in those hunts. Now she has asked/demanded that I find replacements. The alternative is that she will order more sets of headphones. To maintain some semblance of domestic bliss, and to preserve the contents of my wallet, I am humbly inquiring if anyone knows of a source of replacement ear tips. She told me that she tried the local Apple store, and they were of no help. Are replacements available; and if so, from where? I thank you in advance.
