Influx of $75 and $100 airtime cards by years end? | Technical service details | Consumer forum

Thinking about trying to get a free phone, splitting the $100 card into $75 to sell and $25 to keep.

Wondering, since the bonus time promo will be ending by years end, if these cards will be harder to sell (get less then the $60? for em). Since a lot of people I assume would be waiting for the promo to get a new phone and split up the air time cards like I am or just trying to sell the $100 cards since they have enough airtime to last. .
