High prices

Hermes chypre

• 760€ in Hermes Store
• Starting(!!) at 600€ to over 1k on Vestiaire

YSL hobo 5 7

• 2000€ in YSL store
• Starting at 1800€ to over 2k at Vestiaire

Isn't that extremely unreasonable? The pictures aren't even taken to relive my mind of is it fake or not

How do you guys do it?
