Because it's a business that has to make a profit. If you don't like the prices then don't buy anything. The prices are reasonable, but the market changes daily, and can't always accommodate every customer.
Cosmic comics is a great shop and DOES NOT sell fake cards. They will even show you fakes that people tried to sell them if you ask. I 100% trust this card shop Also, Target and Walmart have increased prices on pokemon cards. Good luck!
