Two pieces that were made for each other, priced as a pair. The discount is calm, stated once, in plain numbers - never a countdown.
Or buy either piece on its own - no hard feelings, no tricks.
The saving is stated once, in dollars. No percentage theater, no "was $499" anchor games - the real prices are right there above it.
It never expires. A bundle price that expires is a sale in a trench coat. This is just the price of the pair, every day.
Either piece alone is fine. The bundle is an offer, never the default - the single-piece buttons stay exactly where they were.
Returns stay simple. [Return one piece and keep the other at full price / return the pair together] - Jack sets this.
