You ask a very good question. I'm sure there are pony peeps that would be willing to help you!
My question would be what gen are you looking for?
(My Mother-in-law was on vacation in FL and picked me up 2 Euro McPonies-g2 and g3 MIP for $10. I don't know if that was a bargain or not, but that didn't include shipping, so my guess is that was OK.)
