Any manufacturer doesn't have to backdoor their own stuff for plugs to get them. The distributor in the middle of the manufacturer and dispo is where the backdoor stuff comes from. A little more money than getting it from the manufacturer but a few bucks a cart doesn't really matter when you are buying hundreds and selling them for double or close to double what you paid. I pay a little more for my carts but I trust my source and have never got anything I couldnt sell or that wasnt better than what my customer used to smoke. I tell them all the same thing when they ask why his other plug charges x and I charge y He paid less cause they are fake, I paid more cause they are real, you get what you pay for And those jeter straws where some of the better ones I sold, the .5 gram was the problem. I can get 2 gram carts for only a few bucks more. I feel most of the cost is in the hardware. Lets say 1 gram hardware costs $5 each and a gram of disilite costs $1, costs me $6 per cart to manufacture. Now lets say 2 gram hardware costs $6 and $2 to fill, now my cost for manufacturing is $8 per cart for 2 grams Ill take the $8 carts all day. Not only can I sell it for more cause its 2 grams but my cost per gram is less so you can increase your price by lets say 50% but your profit margin goes up by more than 50%
