I have 4 aegean upgrade vouchers. I couldn't find comps for this for sale here, so is $50 for each or $170 for all 4 fair? If going rate is significantly higher or lower, let me know.
Also, if I got a United voucher and all it is is is a promo and pin code, is that sell-able? If yes, I have a $150 voucher I'd sell for $125 OBO.
