The HULKMAN 50% off Sigma 1 Guard Series promo code at the top of this page is the lead offer and is best for you when the Sigma 1 Guard Series is the only or main thing in your cart. That promo takes half off that product and cannot be used with any other promotion. If you are buying other items, the 45% off your order code or an on site sale may be a better fit depending on what is in your cart.
Small purchases under $35: if you want an Alpha Bag priced at $29.99 or $34.99, buy the marked deal rather than trying to apply a code that only works on other items. The Alpha Bag deals list items from $29.99 and $34.99 as marked, so your cheapest option is the specific $29.99 Alpha Bagx offer when that model is what you need.
Single Sigma 1 Guard Series purchase: use the 50% off Sigma 1 Guard Series promo code at the top of this page. For example, on a $120 Sigma 1 Guard Series order, the promo takes 50% off (percent 50%), leaving $60.00 and you save $60.00. This code cannot be combined with other offers.
Mixed cart of non Sigma items or general purchase: the 45% off your order promo code applies across the driving and roadside range, so it usually saves more than buying an item at list price. On a $120 cart of qualifying non Sigma items, the 45% promo takes 45% off (percent 45%), leaving $66.00 and you save $54.00. Use that code when Sigma 1 Guard is not in your cart.
Buying sale items or marked down products: the site sale offers up to 55% off apply only to the products shown on sale. If an item is already in the sale at 55% off, that beats either promo code for that sale product because the sale discount is applied to marked items. For example, if a sale item is $200 and is listed at 55% off on site, the sale discount (percent 55%) leaves $90.00 and saves $110.00. Use the sale price for sale items; sale items frequently cannot be combined with codes.
Paying attention to combination rules: the two promo codes each state they cannot be used with other promotions, and the sale and many deals also say they cannot be combined. Pick the single option that gives the lowest total for your basket.
