If you do not offer some form of pre-roll already, it is important to do so. People will buy a pre-roll for $5 no matter the weight, do be sure to try to stuff them full though, but not too full because I have gotten pre-rolls where it was too stuffed to even draw a hit through. But the dispensary guaranteed a gram in every pre-roll. Another tip, if you already have pre-rolls, a way to sell more, faster, is to make sure that you list the strain name on your pre-rolls, and set them out in a mason jar on the shelf in front of the register, or ontop of your bud showcase. So that it is one of the first things the person see's, and make sure the can also see that they are strain specific. If a person sees that when they are walking in, they will say something like "I want an 8th of Blue-Dream, 2g of the Purple Urkle and do you have a j of Space-Queen?"
