My first article sale in 1990 cost me $1400 to produce, and I sold it for a whopping $250. I was willing to take the loss back then on that one to get a foot in the door & considered it an investment in my future.
Today, the IRS would not understand if that were continuing on a regular basis & my wife would long ago have left me.
And, both companies I currently sell to have scaled back on their pay rates because of the economy. This is not a highly lucrative job for most of us.
No huge rifle accumulation at my house, I have to pay for one if I keep it, and if I do that it'll typically blow the profit from two articles, if not more.
On occasion I'll buy one, either for personal use or to recycle in another article down the road, but it's not at all cost effective to tie up money in large numbers of more or less standard guns (classics & customs are another matter) that just sit in the vault, and I don't have the time or inclination to be selling a bundle & generally losing money on 'em in the process.
