USA Today:  “The legal sales have spurred heavy demand, and some smaller stores have reported either rationing sales or running out entirely. Prices have changed accordingly: . . . the retail price of pot leaped from about $2,500 a pound to $6,000 a pound within days of Jan. 1.  State and local taxes add up to about 20%-25% of the purchase price, depending on location, and vendors are allowed to charge whatever the market will bear. Customers from across the country have flocked to the Denver area, where most of the stores are located. Some smaller communities have banned sales, while others are developing their permitting processes.”
