ok i just ordred 3 t-shirts which were 30 bucks, then the shippin was 4.38 or whatever. So the total would be $34.38.

Now I put in my gift certificate and it subtracted 50 dollars from the cost.


so the total price is 0 dollars, and i should have roughly 16 bucks remaining on it.

Do I lose that 16 bucks, or can I use my remaining money on it again?
