Why the sudden price increase?
284444
This is more of a related comment than a direct answer, but it's probably following the basic laws of supply & demand - either the demand is going up or the supply is going down (or both). However, it's a bit absurd now to pay $83 per Gigahash with the Bitcoin network difficulty so high (based on a price of $27.87 each, a speed of 0.333Gh, and a current difficulty of 511M as of 11/12/2013). Considering the massive increase in overall hash rate on the network, the difficulty is rising significantly every 10 or 11 days or so. That effect is going to continue too with rapidly evolving technology (one vendor is advertising their 28nm technology for $8/Gh albeit with a significantly larger cost commitment). So although these are cute and fun, the reality is that they are rapidly becoming obsolete, and the prices really need to dive at this point...

You are so right and Amazon had this for $16.54 in October. The price has gone up even more since your post!

Happens with many other items. It's a free market, after all. No sane person would buy at those prices, so who cares!

I got it for 499 this morning... an hour later, when my friend decided to purchase it also, it jumped 50 bucks.

Due to shortage in inventory , distributors have raised the price. it should be back in stock soon and then the price will go down again

It has risen from $1469 to $1499 a couple of days ago. I managed to get it at the old price, beating the increase by a few days. Might get higher by February, the $ is in really bad shape worldwide and no end is in sight of it's fall.

I don't get that either. I always buy from this store and today I found out that it has increased by more than 100%. What's up with that? I bought it regularly, but I won't ever again.

The price increased from $1,631 to $1,742.97, and now increased again to $1,815.44. I actually had it in my cart to order it in the next few days, but I just removed it after the price change.

We are running low on inventory. As the quantity of inventory decreases, the price increases. Otherwise we would sell out completely. Our prices on all marketplaces, including eBay, have increased as well.

I just noticed the price increase!! Last time I ordered the 24 pound bag, it was around $24. It is now over $40! Crazy! What happened??

Hello, It could be that the price changed to the pricing from the supplier. We apologize. Thanks

I have been following this item and pricing too. I was wondering what caused the price to just double. It must be an error.

Fast forward to today and the price just went up from $398 to $598.........but it was only $398 a couple of days ago.

I can only assume that it is due to supply and demand. The new ones are $135+
