Can someone help me double-check my math?

.75-(.75*.077)=0.69225 BTC # Cost each by going for the 7.7% refund

((.75*2)+((.725-.075)*2))/4=0.7 BTC # Cost each by going for the 10%-off coupon on Batch 4

Price required for 10% coupon to be a better deal than the 7.7% refund: ((.75*2)+((.7094-.075)*2))/4=.7094 BTC

So if my math is right, for taking on the added risk of buying twice the hardware we've already purchased, the price per MOQ would have to drop to 1.4188 BTC to be a better deal than just taking the refund.

That's a price drop of 0.0156 BTC/each, so probably the next batch. But when will that next batch ship, and will it have improved DC/DC components? These are questions that really need to be answered by Bitmain before I take their coupon. That, or they need to be more aggressive with their coupon offer, otherwise I'm leaning toward opting for the refund, since the chances of me being able to order double what I've already ordered are slim. My primary hope would be to resell the coupons for more than .05775 BTC, which I doubt will be likely unless something extra-ordinary happens to the price of BTC for the duration of the coupon.

Anyway, how does my math and conclusion look to you guys?

It is easier to calculate on 2 S3 ...MOQ...

I paid 1.5 BTC ...batch 1 ... 1.5 BTC x 7.7% = 0.1155 BTC refund for Batch 1

Batch 2 & 3 will be similar...

NOW next batch is 7.7% LOWER performance...it should start @ 1.45 BTC - 7.7 % = 1.45 - 0.11165 = 1.33835
...or ~1.35 BTC per order - to be FAIR and consistent with current performance level...

This is my expectation ...correct me if I am wrong...

We'll see...

Of course, see the surge in hashing between yesterday and today. They are assembling batch 2, then "testing" it.

Like it!!  And 1.35 - 0.15 coupon = 1.2BTC

Your third line has the wrong value at the end.  Should be:
Price required for 10% coupon to be a better deal than the 7.7% refund: ((.75*2)+((.7094-.075)*2))/4=.6922 BTC
Otherwise it looks about right.  How did you arrive at .7094?  There is probably a slightly higher cost that would yield .692249 which would really be the point at which it becomes cheaper but you don't show how you got .7094 as your price point.

Exactly ...if I buy next batch for 1.20 BTC + 1.50 BTC paid for Batch 1 = 2.70 BTC for 4 S3 ...

This should be average of 1.35 per purchase (2 S3's)...which is FAIR...I guess...

EDIT...:

Do you agree with this math, BitMain...

I hope they don't agree, and factor in a months diff increase, for another 0.1 off..

Some people seem to think the coupon is 10% off from next order, I interpreted it as a coupon worth 10% of your old order value so I don't really see why people are trying to calculating stuff. It's easy, take the 7,7% if you don't know if you are buying more S3s, if you plan on buying more S3s just take the coupons.

I was thinking the same thing.

10% coupon is calculated based on your PREVIOUS, OLD order...not your "future order(s)"...

Read more carefully ...

quote from the 14th

Some thoughts on the maths of the 10% discount voucher:-

If a batch 1 order (pair of miners) was 1.50 BTc then the voucher will be worth 0.15 BTc

So a future order for Batch 4? will have a starting price of (pair of miners) 1.35 BTc 

Deduct the market reduction Bitmain have been applying of at least(pair of miners) 0.05 BTc = 1.30 BTc maximum (copied from the Batch 3 price)


Then you arrive at 1.30 Btc less the voucher of 0.15 BTc

This puts a Batch4? (pair of miners) at a net cost of 1.15 BTc

By the time the backlog of orders are cleared, then another market reduction will be needed. (another 0.05 BTc)

By the 20th of this month we should expect to pay no more than 1.10 BTc for a pair of Batch4? miners.

So, we have arrived at the same reasonable conclusion.

Luck plays a factor in this as well.

Guys , I have chosen the coupon option, but cannot see anything yet.

Anyone with the same issue?

If goto the My Applications tab in your account you will see it. Mine shows this: Coupon: AntMiner S3 Coupon 0.075 BTC x 5. Still waiting on it to show up in My Coupons.

[tzortz]

Aah, right.

Thanks so much.

I am curious how it could be X5 if orders were in pairs?
Can you split your coupon/rebate and do part coupon/part rebate. I would do that, but don't see this option upfront.

minimum order was 2

after that you can have as many as you can afford

Log in and look under Applications, mine is listed under there.

I see. I guess I did not see this option because I placed several orders, each of 2 miners.

So were they just lazy today and decided not to ship any?
