Is there a way to make it calculate how much 
someone should send if the person sending it is 
paying for the fee as well? For example: Say the 
base amount in question is $10. By your 
calculator, the total fees on that (using 2.9% + 
30 cents) would be 59 cents. But if the sender 
*sent* $10.59, you would be charged 2.9% on the 
extra 59 cents. . . Obviously, that would be a 
negligably tiny amount in this case, but bump 
that up to $100 and you've got a bigger uncovered 
margin.

But in any case, are you leaving this page up?? 
Because I would find it incredibly useful! ^_^ 
Even more so if you could find a way to calculate 
how much would need to be sent to cover the fee 
to the sender. (Since I have a number of Hard 
Rock Cafe "pin pals" who officially don't accept 
Paypal, but will quietly let me use it so long as 
it doesn't cost them anything. ^_^)

Awesome job! ^_^
