REI Outlet cuts up to 75% off a selection of Black Diamond, Marmot, and Prana items. (The banner advertises up to 35% off, but we found larger discounts within.) Shipping adds $5.99, but orders of $50 or more qualify for free shipping. A couple of best bets:
REI Outlet offers the Helly Hansen Women's Pace 2 Half-Zip Long-Sleeve Top in Ebony, Ice Blue, or Coral for $19.73. Opt for in-store pickup to avoid the $5.95 shipping fee. That's $50 off, $8 under our June mention, and the lowest price we've seen. It's available in sizes XS to XL, although not in all size/color combinations.
Fila via eBay offers its Fila Women's Quarter-Zip Comfort Knit Pullover in Grey/Pink, Peach/Blue, or Lime/Blue for $19.99 with free shipping. That's $35 under the lowest total price we could find for a similar Fila pullover elsewhere. It's available in sizes XS to XL.
