Powertap is offering a power meter trade-in deal-- 20% off P1 and P1S pedals-- today through the 27th, which brings the cost down to $960 for the dual sided system and $560 for the single sided system.

It looks like Excel Sports may be offering the discount straight up, no trade-in: https://www.excelsports.com/main.asp...jor=3&minor=33
