Buck Naked Men's Underwear XL brand new not in package

Buck Naked Men's Underwear XL brand new not in package There is a 30% bundle discount on 2 or more items. This is stated on the listing by Poshmark with an area to click. If this pair is bundled with the other pair, as the seller, I see anyone can buy the 2 pair bundled at $24.50. I put a picture to help try to explain.
