Oh come on here! Wah, wah, waa...
First thing is, they aren't a nation wide thing in many grow shops.....Not trusted yet (by shop owners)
Thing is, this is changing.
Folks come on web sites and tout it's greatness. More is sold.
They need more components to make it. Sources change, as do prices for those components (did you know the quality source's for P are declining fast! The quality is going down, the cost to mine and refine is going up. There are around 25 -30 years of cost effective, mineable P left in the world!).
So, source prices are rising.
Uncle Trumpy is fucking up the world markets, so prices are rising on everything. Think manufacture cost's (including OT for meeting production goal's) packaging and labeling, cost of distribution (ever heard of carbon footprint).....
Their demand has risen. So it's costing more, to get it out farther..
Result, prices go up...... Every body does it when they are a start up.....Things will stabilize as they get sourcing and increased production costs lined out....
Quit belly aching over life!
