Exactly WHERE did you see that? Did they have paperwork? I would certainly be suspicious of a het pied female being sold for the price of a normal...why would anyone do that, if it was legitimate? If they had an emergency, and couldn't sell her quick, then perhaps...but that's a one-off situation, not a trend.
If they have legit paperwork and there are more of them, I'll take them. lol
I saw about 4 of them for sale, by different people. All of them had awesome feedback, but you never know... 250 for a proven het female is insane.
