+We are sending a payment of 103.20 to paypal which is what they then use to make the 2.9% + $0.30 fee calculation instead of basing it off of $100. So, the fee ends up being $3.29 instead of $3.20.
+ 
+We need a better formula:
+ 
+A * 0.029 + 0.3 = B
+ 
+A - B = C  
+A = C + B
+ 
+C = 100
+ 
+(C + B)*0.029 + 0.3 = B  
+0.029C + 0.029B + 0.3 = B  
+0.029C + 0.3 = B-0.029B  
+0.029C + 0.3 = 0.971B  
+B = (0.029C + 0.3)/0.971
+ 
+0.029*100 + 0.3 = 3.2  
+3.2/(1-0.029) = 3.2956
