So, I saw a brief mention of this on a separate thread, but didn't get a good idea of how common the use of, for instance, Advanced Reproductive Care (ARC) "packages" for IVF is.

My understanding is that certain clinics have a relationship with this company, which will allow you to "insure" an IVF cycle with a (full or partial) money-back guarantee, and will offer you a rate up-front for 1, 2, or 3 IVF cycles, that would save you money IF (and only if) you wind up needing multiple cycles. It sounds to me a little like you're betting against yourself/your clinic... On the other hand, if the amount for two (up to two fresh/two frozen) were comparable enough to the out-of-pocket, pay-as-you-go rate for a single cycle, then I could see how this sort of arrangement would make sense.

Does anyone have any experience with this? Advice? The actual cost is not available online...they want to be contacted directly...so I'm stalling.
