These are amazing boxers and this is a bit of a hack.
So enter one pair, then click proceed to checkout. A popup appears saying add an emergency pair for $20, click agree and then click the X to remove popup, then click checkout again, repeat until you have 7 pairs. Now you will be charged $84 total, now on the check out page enter code Waist20.
@pirlo thanks 15 pairs for $78, change the emergency pair quantity to 14 and check out.
I need my trunks to have an opening for the boy. Too much hassle having to put them down and up every time you need to wee. Do that for poo only. Never understood people who completely open up their pants when they pee as well along with the belt and all. Saw a few of those in public loos. I just zip out, take out, put back and done.
