I hear you on the sticker shock when boys hit mens' sizes. Ouch! If you are an REI co-op member, you can get 20% of during their member sales. Check their sales section either way to see if there are any listed. Another option is Dicks sporting goods. I've seen several local sports leagues joining with DSG to offer 20% off right now. The coupons are widely available on the league websites so maybe check there for a coupon. Backcountry has a 15% off deal for first time customers. Check 6pm.com for other their prices. Hopefully you will find a good deal somewhere!
