I have to agree with mike here. There is no way they accidently threw a pied in a shipment to petco. A pastel is very understandable however because they can be very similar to a normal. I have seen some normals that have better colors than pastels.
You can get male pastels for around $100 breeding size. So yes $40 would be a steal especially if it were a female. I'm not buying into the pied at petco however thats just ridiculous. Thats like sayin I went through the McDonalds drive thru earlier and ordered a 99 cent double cheezburger and they accidently gave me a filet mignon....Come on now
