I still would like to know how inflation factors in. Also, tax + shipping + FFL. For example, I buy something from GB for $500. Pay the 3% credit card fee that so many sellers have plus 8% sales tax I’m already at $550. $30 to ship plus $20 FFL and I’m in for $600. If I sell a year later for $550, am I selling at a $50 profit or a $50 loss?
