Costco won't buy it back under any circumstances, --which is a very telling clue about the net price of metals these days. For retail vendors whether brick and mortar or internet, the real money is being made on buybacks significantly below melt, --and there are only a handful of venues with the liquidity to make a competitive offer at scale. You might be shocked to learn how much below melt they offer. I suspect Costco's only reason for involvement is as a loss leader to draw new members into their stores.
Kinda like the $1.50 hot dog but on a lesser scale, but not everybody can afford nearly $3,000 an OZ for GOLD, what many dont understand is it is a wealth storage tool. if your going to buy it and then turn around and sell it a couple months later your mostly assured to lose money premiums here in the silver state run about $135 on the buyers side, thats the cheapest I found besides Costco in St George at a maximum of $70 sometimes allot less depending on the market fluctuation.
If only I had the problem that I had to start stacking gold because my silver stacks were taking up too much space!
