+1 to checking softlines at the end of the season (a few retailers have started moving select colors to clearance even as early as now), particularly in March. Generally softgoods don't have MAP and will drop a little earlier than hardgoods. If you know what fabrication you're looking for and what brands fit you well (or how to take your measurements & use their size charts), it's easy to pop them into Google Shopping or Amazon (with their 3P/FBA program that sources from a lot of smaller shops) to find the best price. I've had particularly good luck with Euro brands that have tried to launch in the US where forecasting's pretty challenging for retailers (like Haglofs, Salewa, Houdini, and Millet).
I'd also look at some of the alpine clubs like AAC or Mountaineers - depending on how much/what you're shopping for, an $80 membership can save a lot of money in the long run - AAC's gear discount page is pretty representative of the brands that play and the common discounts. Stock can be a little spotty if the discounts run through Experticity and brands come and go (especially if the offer seems to good to be true), so if you see Black Crows Atrises going for $350, buy them before the discount gets pulled two days later.
