While you buy miners, they buy bitcoins, the bitcoin price raise more fast than the bitcoins you can mine with the miners.
When you send them 25 000 USD for a ASIC, they buy bitcoins, by the time you get your machine, their bitcoins double in price, they make profits. You instead will have to wait much longer to maybe break even.
It's more profitable to sell the machines and buy bitcoins for them than mine for bitcoins.

So I had a choice, buy a bottle of Scotch for $40 or buy 4 Block Erupters for $40. The Scotch would have been fun for a weekend, but the Block Erupters have been fun for 3 months now and I made at least enough to buy a couple more bottles of Scotch. LOL
I bought my first 4 with cash, not BTC and they arrived in 3 business days. The other five I got with the BTC they mined so that was one for free.
BTW, even the ones I got with BTC arrived 3 business days after I ordered them. Of course I ordered most of them from a company in my own state.
