It seemed straightforward enough to me Bob.
If you put in $10 and buy a candy bar for $6 you have $4 credit left.
You can then choose another item provided it costs less than $4.

It just implies another level of loop in the design.

In fact given the detail of the spec its hard to see what we could add 
by way of help until the OP produces some code to critique.
