He won't buy it for himself. You should.
He'll never admit he needs this. Doesn't mean he doesn't. Give him one less job and a bit more time to do nothing.
What he gets
A prepaid Daily wash bundle. Pick the plan that fits his household and how many washes to gift — 1, 2, 4, 12, 24 or 48. He gets a redemption code by email and books his own pickups whenever suits him.
Worth knowing: this is a one-off purchase — no card on file, no auto-billing. He redeems in his own time, and can subscribe afterwards if he loves it, but nothing renews automatically unless he chooses to.
Redemption code delivered by email within minutes. From $72 for a single wash.
