Cabela's takes up to 80% offselect clearance apparel, with prices starting at $4.99. Shipping starts at $5.95, although orders over $49 can score free shipping via coupon code "4TREAT". A couple of best bets:
Cabela's offers its Cabela's Men's Windcrest Microfiber Pullover in five colors (Goose Grey pictured) for $14.99. Opt for free in-store pickup to avoid the $5.95 shipping charge. That's at least $25 off list price. It's available in regular sizes S to 3XL and tall sizes M to 3XL, although not in all color/size combinations.
