That sounds slightly better than the old 1GB in Italy, 200MB roaming, or have I remembered the tariffs wrong and should look up which has the notional €3000 value?

90c/kilobyte = 900 €/megabyte. The Mega package gives you moreless 3.33 MB not 333 MB! Since you pay for this "virtual" 3000 € 20€ only, 1 MB from the packet costs 20/3.33 = 6 €. 1 MB w/o the Mega option costs 1250 cents = 12.50 EUR.
Let's solve a simple inequality (the unit is eurocent)
where:
x - kilobytes over 3.33 MB,
LHS - cost with Mega
RHS - cost without Mega
2000 + 90x > 4166 + 1.25x
88.75x>2166
x>24.41
So, if you exceed the Mega packet by 24 KILOBYTES ONLY, you'll pay more.
Moreover, let's consider low usage:
1.25x<2000
x<1600
Below 1600 kilobytes you'll also pay less with the regular rate.
The "data usage interval" for which Mega is cheaper than the regular rate is (in kilobytes) [1600,3357]. The maximal saving to be achieved is about 21.66€, when the packed is all used. In this case, however, you face the risk that each kilobyte extra will shoot the costs to the horrible level.
Of course, these calculations are a little rough (I assumed 1 MB =1000 kB, not 1024 kB), but I hope you'll agree with the general conclusions...
