The folowing price is for the 4GB Sansa Clip+
If the order is between 5-10 pieces then KMD will do it for 2500 shipped.
If the order is above 10 pieces, then he said he can do 2400 shipped.
Honestly, I don't think it makes a big difference. I'm sure most of you have 2GB and 4GB MicroSD cards lying around from older phones. Just pop them in. Worst case scenario, I'm sure you can get a 2GB card for like 200 bucks. Still cheaper than getting the 4GB version.
