Revised sharing spreadsheet on line for this group-buy checking list

Count me in, but I can't access your Excel Spreadsheet?:confused:

I'm in - I can't access the spreadsheet though.
Location: 英国

Thank you two.

Wish the sheet is working now, by sharing to gmail users (i.e. on accessing the spreadsheet, you will have a gmail account first).

https://docs.google.com/spreadsheets/d/1QDTI9pfyCdG7QogvuhmoViv5he7IWO17neMqL3zHvic/edit?usp=sharing :D
 
ePacket(to USA), SFexpress, PayPal deal commision ...

It is also saying ePacket is faster and cheaper than HK Post. Maybe it would be a very good news to mrsavage or other ones in USA.
But as a pity, ePacket is only access way from China to USA, not to any other destinations :eek:

HK of Taiwan friends, you knows well SFexpress or other shipping fastern / cheaper logistics, no need neither HK Post nor ePacket.

And I'm still wondering whether PayPal's 4.4% selling commission (<<< click to view PayPal policy) is real.
If it does not happen finally, don't worry, this additional 4.4% of amount will be sure to return back to each one's PayPal account. :D
 
Please remove me from the spreadsheet. I am not interested in this group buy at this time. Take care.:mad:

Sorry reply late, because sometime is not easy to access international internet. Pls understand with thanks.

Okay it was removed. Thank you for your interesting on it. :)

And PayPal account yrpp@hotmailcom is already in J6 of the spreadsheet, while the sheet was created in January. Maybe you don't see it but fine. :D
 
Countinue this Group Buy for another 3 months, etc.

Continue this Group Buy for another 3 months and give more details about your circuit boards. The idea is to develop more interest on diyaudio.com. This way
you might get more people into the Group Buy. Take care ad good luck.:)

En... Seems a good idea. Spreadsheet has a new page GB_20150308 for these months. Would you be the one in this GB? ;)

About more details, there are really some, for what once again I have to try to learn some technical expressions, in order to explain it correctly. If not, I have to make pictures once again and hope that helps.:camoufl:
 
La Mer,
I am interested - I could access the spreadsheet (after logging in), but was not able to add my name.
Thanks!

Hi dudaindc,

thank you for interesting. Your name was add into the spreadsheet.

Because the sheet has some fuctions which calculate result correctly, in order to avoid some misunderstandings, the sheet is not able to be edit exceipt of me. Please check mentioned spreadsheet, and thank you for your understanding.

La Mer

===================================================
