How is shipping calculated?

Shipping Cost    0.868 BTC is something quite extreme!!!

Hello Everyone,

S4 B1 has been already shipped out on Sept. 29th, and it is no shipping in the following days from Sept. 30 to Oct. 6th due to the Chinese Golden Week.
B2 will go on sale at 22:00pm Sept. 29th, shipping starts on Oct. 10th Beijing (UTC +8 Time Zone).

@BITMAIN, the question is now what to become of the S3+ B10. Even with the price of the S4 going down, it's not for everyone. Can coupons be used on the S4 B2 (I don't have any, but I'd ask for some if I'd order some S4)?

[IYFTech]

These new AntMiner S4 units should really kick ass.

It would be helpful if Bitmain actually answered some of the many questions that prospective buyers have asked, instead of just guessing that they "should" kick ass. For example:

Are they still using the old cgminer version? If so, why?

Where is a link to the firmware?

Are these compatible with p2pool?

Plus the many others on this thread. Bitmain are selectively answering only a few of their customers questions whenever they log on, but ignoring most of them.

Come on Bitmain - let's have some answers & support please!!

Bitmain - instead of logging on to announce another batch sale then logging off again, how about answering some questions? I don't want to buy something not knowing if it will work with p2pool or not, or weather it's running old, security vulnerable software or not.

Why don't you answer any questions!!??

Hi,

Latest version of Cgminer has been uploaded to https://github.com/bitmaintech/cgminer, which supports S2 and S3. Our R&D team is testing the latest firmware, we will upload it to our official website once it is ready.

Thanks!

Thank you -what about p2pool compatibility?

Please can you provide detailed instructions for users who want to update their S2 cgminer versions to the latest version - thanks.

Price is better at 1250 if you could still use coupon ........ But since you can't then I will still pass btc is burning a hole in my pocket.

With shipping (at least to the US) we're looking at 3.18 BTC, which still equals a negative ROI unless difficulty breaks it's trend. 

Yeah but if you could of slapped on an extra $200 off then it would make it a better deal! still just a tad over 4 btc for me to the UK then plus VAT

[edonkey]

Without a coupon, and with US shipping, and with free power, and 15% difficulty, the S4 is still squarely negative ROI after a year.

Unless difficulty stagnates, these will lose BTC.

For the expensive shipping area, or expensive import tax area customers, I would say host these units or use Bitmain's cloud hashing from Hashnest.com  or Umisoo Hosting in China.

I hate to say this way, but pricing and tax are different all over the world and some countries are Miner Friendly and Some are so-so and a few are far-far-far away from the Miner's Dream Land.

P.S.  

You can use original $200 discount coupons that were handed out to the previous S2 buyer for Batch 2 order.  I think some of them are selling those coupons.  I would say donate some to those who are selling the coupons and take advantage of before the coupns expires.

BUT, PLEASE REMEBER!!  BITMAIN OFFERS NO REFUND, if the miners are rejected or stuck at the customs at your country's end.

RMA is always, you have to return the damaged item to Bitmain, then the replacement parts will be send to you.  If the misconfigured units are returned to Bitmain for RMA, the shipping fee will be billed to you, so lets do some basic diagnostic before send the units in for the RMA.  Some cases, Bitmain does offer Advanced RMA where you can pay the deposit for the parts, case by case I think.  Not avaialble for every RMA.  

Without a coupon, and with US shipping, and with free power, and 15% difficulty, the S4 is still squarely negative ROI after a year.

Bitmain, thanks for the recent price drop but do you have a decibel reading you can provide on the S4 and when will you release the S3's for sale? Thanks.

If the price doesn't stop dropping and start coming back up, difficultly will stagnate.

0,73 shipping costs to my country for two S4s? I like your products but this is insane. +20% customs duties.... better byu some BTC and wait.

You in the UK? i got a quote earlier for one at .88 i wonder if 2 is the same price, means better getting together with someone else and ordering together so save on postage if thats the case.

[analoxide]

Bitmain Definitely Listened this time, IMHO....

Wish it could be a bit cheaper but

S4: 2000GH @ about $1420 (Shipping Included + 1400W PSU)  $0.71/GH
----------------------------------------------------------------------------------------------------------
SP20: 1700GH @ $1309 (Pre-Order Shipping Included)  $0.77/GH  WITHOUT PSU
----------------------------------------------------------------------------------------------------------
AM Prisma: Price varies & Does not come with PSU


And if Batch 1 customer wants to buy B2, they will receive $50 discount coupon,
so it will be $1370 ($0.685/GH with PSU & Shipping INCLUDED)

Also, the cusotmer who has not yet used $200 coupons from S2 purchase history,
that is another $200 discount on top of $1250 price.  ($0.61/GH)

Another Benefit to "NOTE" for Bitmain Antminer Products...  If you are in North American Region, RMA is handled within USA, if you are in EU, RMA is serviced from either UK so no double tax.

Russia & Former Soviet Union Countries...  Buy these at your own risk, as your customs may not like these miners.  

1250 it is... go go go

I see no place on their order forms, or a way for that matter, to use S2 coupons to apply to the S4 to get another $200 off besides the coupon they just issued for $200. Can anyone confirm that they are allowing S2 coupons to be used for a discount?

I believe you can only use a single coupon per order--they don't stack.

I like the design, the PSU and I think it can be OC'ed. If you don't count the energy costs in, you can get positive ROI in a couple of months.

A "couple"? Two? No chance of that. Here's an optimistic calc with 10% and lower difficulty increases.

http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=34661425924&dcosts=1450&diff_mincrease=10&blpbtc=25&dhsmhs=2000000&diff_mincreasedecrease=3&btcusd=413.24&dpowcon=1200&btcusd_mincrease=0&pcost=0&calcweeks=32&dleadtime=0&action=calc

Break even in about 8 months if you have free energy and have 100% uptime. If you pay for energy you never break even.

Seriously? You're arguing that 8 months constitutes "a couple of months"?

Is it worth waiting to see if they go down in price? I have 2 x coupons to use.

[PatMan]

THIS.

Please Bitmain - answer the question.......

Also:

Our R&D team is testing the latest firmware, we will upload it to our official website once it is ready.

Aren't you supposed to test the firmware before shipping them?

[Sandhog]

I'm in the same camp as you. Perhaps, BTC will rise and S4 price drop and we get the benefit of make our ROI like smart miner should.

I still like S1 and S3 is better. And those make great space heater when weather is getting colder.

I agree with you my 2 S3's continue to hash away nicely at 500 Gh each. I had 3 others but I sold them foolishly now I regret that! I put the money into some cloud mining and I have some GH in Hashnest.

[sushi]

YES!!!

If you have the valid coupns in your account, you should be able to select either $50 B1 customer coupon or $200 S2 coupon.

If it doens't work, PM me and I'll manually process it for you.
