Okay, I confess. I already made the decision and delivery will take place later today.
Free delivery was available this week. DH could have picked up and installed appliances himself, but he's been working odd hours and may be working on Saturday, so delivery was a plus.
We wanted matching appliances, and once DH insisted on a pedestal for the new front-loading washing machine, I decided to prop up the dryer too. So a new washer, a new dryer, and two pedestals will be delivered and installed.
We may sell the old dryer to recoup some of this extravagance. DS has gotten something free through Craigslist before, but we've never sold anything that way.
