I remember my very first visit there very well and after I told that guy on shift about my approach I was recommended Caramel(back then 9€)which I bought as well as Chocolat(10€ back then)and Noga(15€).
All great stuff especially latter one(pocket microscope
So regarding prices I think they just reduced the price(and 'of course' quality. The least a coffeeshop has to do! In my experience just not the case often, especially weedwise)as most people go for their cheaper smokes on offer.
I don't think they did it because they ran out as I'm convinced they're well connected
Don't want to start an argument but I don't buy that 14€/g story it's pointless anyway as dutch coffeeshop prices(or us-dispensaries)are too damn overpriced in the end of the day(it's at best all about inspiration) so taxfree black markets are the place to go
