DENVER | Call it Green Friday — a new Colorado tradition of marijuana shops drawing customers with discounted weed and holiday gift sets.

At Denver Kush Club, about two dozen customers were lined up in subfreezing temperatures and snow showers Friday morning to take advantage of the shop’s doorbuster deals.

The first few customers got free joints, free rolling papers and a T-shirt with purchase.

All medical customers were offered ounces of marijuana for $99 — a savings of about 50 percent off some full-price bud.

The shop blasted reggae music and welcomed the crowd with Green Friday welcome cheers. Similar deals were offered last year, the first in which retail recreational marijuana sales opened.

These stores don’t have to worry about online competition. Internet marijuana sales are still prohibited.
