IVF Drug Costs

I've just been looking into prices for IVF medication for our forthcoming PGD attempt (No.2). If I'd thought there would be a standard price for the different drugs (fyi this time I'm doing the short protocol rather than the long protocol for No1) , then I was much mistaken. As you can see below, the price variations aren't small, they are HUGE. It's a Moroccan bazaar out there! (numbers green are the cheapest prices and those in red are the most expensive)
