Kosmos charges sellers a service commission on each completed sale or rental, shown in your seller dashboard — delivery fees are never part of that commission, they go to the seller/rider. If your delivery district matches the listing's, the delivery fee is included in what you pay at checkout, no surprises. If it doesn't, the item price is all you pay upfront — the seller sends a separate delivery price afterward, which you choose to accept and pay or decline (see "Delivery, self pickup, and delivery fees" above). Either way, nothing is ever charged without you confirming it first.
