I've never even come accross shwag (unfortunately?). All of our prices are usually pretty much the same -
Ranges (that I've spent):
15-20 for 1g/1.5g (is 1.5 an odd way to sell it?)
45-55 for 1/8
95-100 for 1/4
145-150 for 3/8
I've never bought more than 3/8, but as you can see there isnt much of a 'discount' anyway. Eventually maybe someone will tell me where I can find a home-grower to buy from, but I havent yet
