A bidet attachment is less than $50. It's also a one-time cost. Having to purchase wet wipes will eventually cost you more. Also, you're still just smearing poop allover your bum with a wipe. The bidet's jet of water effectively blasts your area clean. Think about it like this: if you cook a spaghetti dinner with meatballs and tomato sauce, would you wet wipe the plates and put them back in the cupboard? Of course not, you'd give the dishes a proper rinsing under a stream of water. I will never understand the aversion to bidets. Anything less is uncivilized, and quite frankly, disgusting.
