Target has 25% on the website, free shipping on orders over $25, and an 10% on select items with coupon code: LABORDAY
REI has 30% of items on the website.
Gander Mountain has $20 off orders over $100 or $50 off orders over $250 using code: LABORDAY50
BassPro has free shipping on orders $75 or more. I also believe BassPro has free site-to-store shipping as does Cabela's.
Aim Surplus has sales on the website that need coupon code: LABOR DAY
And it appears many other sites have special pricing online, no code or anything needed.
