A couple of points on the con side of discounting and pricepoint pricing. First, in discounting, there is the slight chance the guest will say in his glowing review for future guests to see, "@Malcolm16 was great! He gave us a sweet discount!" More likely no review at all though, so you're safe there.
In pricepoints, if you make $500 your pricepoint, and so show $439 on the listing, there are those who will see the $439, and want to pay that. "I didn't want to pay $500! It says $439!" It might be better if all listings showed the amount the guest will pay right up front, but I'm not so keen on it that I want to make it a Host Voice post. There is the problem of cleaning fees, etc., and I have no solution that won't surprise someone who thinks he will pay only what he sees beside the IB lightning bolt, sans taxes, cleaning fees, service fees.
None of this was your question, though, was it, Malcolm. You just wanted a figure to work from, and you got it. But you asked such a good question that it sprouted tangents!
