One obvious optimisation for where GPRS may be very expensive is to 
simply send a SMS, compressed according to a shared database.
ABC = Item 28, 3 of
EGI = Item 187, 10*100ml of.

Some 60 items per SMS, of a list of several hundred is probably suitable 
for most people.

In most cases, the fact that you're going past the store is pretty 
irrelevant to the need for groceries.
