The correct calculation should be on average:Raficoo wroteMTC BB service = $40/month (100MB)
ALFA BB service = $9.5/week (24MB)
100MB/24MB = 4.17
$9.5X4.17 = $39.615/month :|
30 days / 7 days per week = 4.28
4.28 * 9.5$ = 40.714/month for alpha
Or you could divide the 40$/month and get 9.37$ per week for MTC. You will notice that the price ratio (4.28) is close to the quota ratio (4.17).
In simpler terms, both offers seem identical to me. (Maybe Alpha is a little better because it gives you better flexibility).
@Monkey, start another thread. :D
