Yeah somethings are good while others are bad. Cabelas Clothing is a big discount around 30%. If you used it on reloading supplies it brings them down to what we normally pay. The $100 off $500 are usually much better.
When our Pheasant's Forever chapter buys things they give us employee pricing and it amounts to 40-60% off cabelas brand, and 20-40% off other items. Guns, electronics, bows, not much of a discount. I purchased a Nikon muzzleoader scope last year using the discount card and saved about 25%.
