Terry has a 50% off selected styles sale as the top offer on the page, best if you are buying one of the qualifying women's pieces that are marked down. That 50% off sale applies to selected styles only, so it is the main saving for shoppers who find their items in the sale selection.
Small buys under $100 If your cart is under $100 and includes one or more of the selected women’s styles, the 50% off sale is the one to use because it directly reduces the price of eligible items. If your cart is under $100 and contains no selected sale styles, there is no active promo that lowers the price; you will pay the listed price and shipping will apply.
Orders just over $100 If your cart includes selected sale styles and subtotals more than $100 after prices are applied, you get the 50% off on those items and you also meet the free shipping threshold, so you save on both item price and shipping. If your cart is over $100 but contains only full price items that are not in the selected styles, you do not get a price reduction, but you do get the free shipping for orders over $100.
Buying mostly full price items If you plan to buy mostly full price items that are not part of the selected styles, the only active saving that helps is free shipping when your order is over $100. The sale does not apply to non selected items, so check each product page for the sale badge before relying on a price cut.
Buying from the sale selection only If every item in your cart is from the sale selection, the 50% off applies to each eligible piece on the site only, and you will pay half of the listed prices for those items. If the sale total also exceeds $100, you will receive free shipping in addition to the price reductions.
When you choose between the two offers, take whichever leaves you with the lower total for the same cart. The 50% off sale reduces the price of eligible women’s styles and is the stronger saving on marked items; free shipping over $100 only saves your shipping cost and only applies once your order subtotal is greater than $100. There is no stated rule on combining beyond the site terms, so your best approach is: use the 50% off prices on selected styles and aim to reach $100 if you want to add free shipping as well.
