usually every day they offer several strains and lower price every 10 mins till someone buys that strain an then the price goes back up and then it starts back down......then sometimes they put their whole catalog in the reverse auction and then they lower the price every hour...they put the price up higher when it starts but it lowers every 10 mins or an hour...i find some good deals in the middle of the night..lol...or b4 noonish..when less people are up an lookin to buy beanz..GL
