The only significant difference is 3 versus 0 callbacks per month, which is a factor of infinity higher, for only about twice the monthly fee.
Other than a factor of two difference in a ridiculous amount of disk space and data transfer.
You can always upgrade plans later, although there is some chance this "special" deal won't be available. There's also some chance they'll add callbacks to all plans, or reduce prices.
The important thing is to use a $97 promo code.
