Right. However, from the 505 e-miles I have, I'd say only 100 came from genuine earning opportunities - the rest were from the initial surveys. I'm going to assume for now, that this is not going to be so profitable and getting 500 miles every quarter is probably not gonna happen. So, I'm going to forgo earning more e-miles in March, thus hopefully keeping those earning opportunities available to be earned in April (meaning they get extra 3 months added to their expiration date).
