Buying stamps half a dozen at a time reduce first class rates to $0.85; businesses using postage meters will get $0.75. Not cheap, and still a big increase, but the $1 rate will be paid by a very small number of people too cheap to buy stamps six at a time.
As for home delivery, it'll be sad to lose it but the alternative, the community mailbox a few doors down from most houses, will have one advantage: parcels will be loaded into it for you to pick up. Currently if you're not home you have to drive to the nearest sub-post office to get your parcels. This will be way more convenient.
