What did Jesus tell the folks from Laodicia to buy and sell?  
Revelation 3:17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked:
18] I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see.
It's your choice Laodicea! The Lord says "I counsel you to seek "spiritual gold", that has been purified in the fiery furnace whereby the slag of sin has been removed by your seeking His sacrifice... and the pure white raiment of righteous acts, instead of those black wool suits you so covet, so that when the true Messiah, Jesus Christ, returns, you aren't standing there stark naked before Him and the host of heaven He brings with Him, and you're scrambling to find some rocks to hide behind, wishing they'd fall upon you and end the awful shame."

And these "spiritual items" cannot be purchased by cashing in your IRA's & 401 K's, and your inflated Bonds & Mutual Funds, for all the riches of man combined cannot purchase even one soul.

It's your choice Laodicea! Anoint your eyes with a poultice (a soft, usually heated and sometimes medicated mass spread on a cloth and applied to sores or other lesions), that they might open up and now you have "eyes to see".
