it is impossible to buy cheap things to resell for a profit

[_MVP_]

no one sells cheaply anymore

i mean why would they sell you cheaply if they can sell more expensive to someone else?

arbitrage opportunities do not exist

 

[_MVP_]

same thing its impossible to sell something expensive

people would just buy from where its sold cheaper.

this eats away all profit, profit margins dont exist

the market is efficient

again, no arbitrage
