How cheap could you get 1,000 2GB SD cards ?

After checking out the "humane reader" http://blog.makezine.com/archive/2010/07/the_humane_reader_a_20_computer.html

I thought a much better product could be made with the propeller. For now I call it "Rising Tide", from the saying that a rising tide lifts all boats.

I've gotten pretty much all the costs down, but I have no idea how cheap the 2GB SD card would be ?

I'm sure you can get them cheaper than you can at a retail store, but how much cheaper ?

I guessed at $6.00. But I don't know how realistic that is for 1K pcs.

Someone correct me if I'm way off on any of these prices or if I forgot anything.
These are 1K quantity prices by the way...


Required Hardware:
  PCB                               1   $ 2.00 Guess
  Propeller Chip                    1   $ 6.00
  Crystal 5MHz                      1   $ 0.41
  EEPROM (32KByte) Pre-Programmed   1   $ 1.04
  Mini SD connector                 1   $ 0.44
  RCA Video Jack (yellow)           1   $ 0.33
  RCA Audio Jack (white)            1   $ 0.33
  USB connector                     1   $ 0.87
  Push Buttons              $0.20   5   $ 1.00 Guess
  3.3V regulator                    1   $ 0.30
  Passives                          ?   $ 1.00
  2GB SD Card W/Content             1   $ 6.00 Guess
                                       --------
                                        $19.72

    I've bought them on sale for $5 from Radio Shack around holidays when other people would be doing stuff or traveling.

    I found this one for $5.40.

    http://www.amazon.com/gp/offer-listing/B000J47W12/ref=dp_olp_new?ie=UTF8&condition=new

    The truth is that buyers in bulk probably won't tell you.· The company I work for has salesmen and·our accountant and I feel that even though a lot of people want a deal, they can only sell it at the same price.

    I've heard a salesman say he left a company after showing people the truthful price of a product because the boss wouldn't allow it and the salesman didn't want to look dishonest to his customers so he left.

    You can probably get a good price if you don't buy a name brand but when I look at stores, there seems to be the same price where they want the price to appear fixed on memory cards.· For example, I can buy a 8 GB thumbdrive for about $20 and a 16 GB thumbdrive for about $35.· If the price is "fixed" then why shouldn't the price be $40 for 16GB when the 8GB is $20?· Why is it $5 off for twice the memory if it all costs the same?· My guess is you can easily get an 8GB thumb drive for $15.

    I think it is important to know the markup.· The markup is what employers charge or otherwise any sale isn't worth it to them.

    I also bought shoes from a discount shoe seller.· The malls came in and bought the shoes, added boxes and marked up the price.· Salesmen came in from the major and name brand shoe companies and said, "We won't sell to you because your prices are too low."

    Judging from Mouser and others, I suspect a good price break might require a purchase of more than 10,000 units.

    Some items just aren't interested in 'small deals'. I learned this with printing T-shirts. We had to buy a minimum of 10,000 before the price created any opportunity to make money.

    I've noticed a bottom-line sale price ~$2 per GB of flashdrive storage. So $4 for 2 GB, $16 for 8 GB, etc. This is for retailers like Fry's when they have a sale (usually with a limit of 2, not 10,000!).

    If you dare to enter the jungle in your quest, here's one portal you can try:

    Just beware of counterfeit goods and pre-installed malware.

    I tend to get my budgetary prices for memory from http://www.dramexchange.com/
    Even in free mode, you can normally get spot & contract prices - including SD and uSD.
    Unfortunately, the lowest prices you see in retail are _less_ than the volume price...

    Bean,

    You forgot to cost the Battery Holder and the Assembly costs.

    Bean,

    The other thing to consider is when you buy a digital camera, they sometimes come with internal memory and a 16 MB card (not Gigabytes) giving the user functionality but forcing the user to buy it himself.

    Do you know if I were to buy a large SD card from Canon it would be about $99 and there is nothing special about their memory cards.

    I think they have the right idea to let the user·bare some of the costs.

    @Bean,

    I'm pleased that I'm not the only one who was starting to "run the numbers" after seeing that $20 'puter.

    Question. I don't see PS2 jacks. Are you thinking USB keyboard?

    Sorry to bother you again.· I think you can get the tact switches for four cents or less.

    Bean, a little birdie told me that a recent purchase of 1,600 Sandisk 2GB SD cards was made for $6.55 each through CDW. Sandisk P/N SDSDB-2048-A11. Not the cheapest price "on the net" but it came with a cert to guarantee SANDisk origin as well as quality.

    I wouldn't dare buy SD/MicroSD or any other memory card from Alibaba, DealExtreme or any other Chinese-based outfit as faked cards are so prevalent.

    Chinese manufacturers won't hesitate to hack 'old' .05 or 1GB cards and reprogram the controller to report 4G, 8GB or even 16GB. And if they can put a 'reputable' logo on them, they won't hesitate to do that, either.

    It seems their business strategy goes something like this 'As long as we get your money we don't care if you never shop with us again, there's enough other suckers out there we can also swindle'

    And yes, this goes all kinds of flash cards.
    I have a bundle of '8GB MemoryStick PRO Duo' which diagnostics reports to be 1GB and of very poor spec, too.
    (No, I didn't buy them. Someone at DX screwed up and added them to one of my packages for 'free')

    There is no battery back. Power the thru the USB connector. User is responsible for a USB power source.

    No PS/2 connector on the bare minimum version. I can vision two version. One is the absolute bare minimum for functionallity. And a "plus" kit that has some extras like PS/2 keyboard, USB power supply, RCA cables, etc. The PCB will be same. The product would be sold as a kit, with all thru-hole parts. The user would assembly it. Possibly a different PCB could be made with all SMT parts that is pre-assembled.

    Bean,

    If your plus kit would let me edit files using a simple text editor then it would be useful for me because I bet that unit would boot pretty quickly, be portable and it would let me take it wherever I go without paying for an expensive Netbook.

    I've seen the "Lightstick" for the Nintendo DS which is basically a battery box that holds four AA batteries and it connects to the Nintendo DS with a USB connector.· I'm not sure which USB connector it is.· I bought one at "Five Below" thinking that I could power some of my projects.
