Since the first show I have been to back in 2004 till present, the only morph I have seen even remotely come down in price are Pies and by 50%.... no way. Maybe 15-25% tops. Thats here in the D.C./MD/VA area.
Pieds are down 80-85% from 2004 prices. Spiders were several thousand and are now $100-175. Pastels were still in the $1000 range and are now $50-150. The list goes on. Everything is about 5-20% of what it was in 04.
