Boss man's mark-up is 20%. That's $20 per $100 of wholesale price. For those of you in Rio Linda a gun that costs him $400 at wholesale will ask $480 in the case. Mark-up on just about everything bought wholesale is 20%. The USED guns may be bought for just about anything reasonable dependent on the seller and will be marked as close to fair market price as can be determined. Of course there must be room for profit...
