I don't see dropbox on there. Might be interested as well, if you can lower the rates.
If you buy in bulk then I can lower it. We can negotiate the amount how much you needed.
Perhaps you can tell me the price of bringing a new account to 17 GB through referrals, which is the max allowed. I think its around 30 referrals.
You will get 1 GB per ref.
Now I will give you 1 ref for almost .8$
