looking for softcups

Ladies, my wife and I are on month 5 of ttc, and we've been using softcups to hold the sperm inside for up to 12 hours because several of our friends had success with this. Problem is, suddenly I can't find softcups ANYWHERE. All online retailers seem to be sold out- and we had been buying on Amazon up until this month. We need them within the week- does anyone know of an online store I could find them? Not a single local retailer carries them.
