GOLD? I wouldnt fuck with that now. If it was still at $300 an ounce and u had the time to wait then maybe, but nowadays? Nah!
Shit is over $1100 for an ounce. The way you guy em is buy Krugerands, they are the coins. Depending on where you are, may find em locally.
As for the other poster, I personally do see loot online and would consider with what you have at hand to make alot of money with a physical product but using the power of the web to promote it.
Case in example, ExtenZe sex pills. They are only a herbal medical pill made by a company like
http://www.nutricaplabs.com
They make your product, package it, store it and do product dropshipping.
You then need the customers right? You can go to an affiliate site where you submit your product for sales, would need a sales page and company to handle the ordering also.
Affiliate sites for submitting this wonder pill or cream is like MarketHealth.com, CJ.com, Ads4Dough.com
those are just a few...
OR...
If I had that money, I would prob fly to china when they are having these big product display conventions. These guys have the simplest inventions, but make money if you brought it to America and mass marketed it. Case in example the PedEgg. Piece of plastic dont even cost 50 cents to make, but sells for $10. They have tons of inventions over there and would be more than happy to slap your logo and packaging and ship you thousands and you set up a warehouse here and make sales to Walmart, Target, Kmart...
You get the idea.
