Sorry, I value the ray at 30, which is why I said you're about 10 off, and most people here sell Skyla at 25. Even by your values you're still off by at least 5, so I'd kinda like to make the trade bigger to get some more out of it.
Sorry but I'm not intersted then. I can get a ray for 25 on ebay right now, but the lowest I could get a skyla is 29-30.
