Maxwell and Geraldine is currently showing 30% Off Sale Styles as the lead deal, which is best for shoppers who are buying items already marked as sale styles and want the biggest percent off those reduced items. The 30% off sale styles applies site only to selected sale pieces while stock lasts, so use it if the item you want is listed in the sale.
If you are buying a sale dress or other sale item. The 30% Off Sale Styles is the clear choice. For example, on a $120 sale dress, 30% off reduces the price to $84, so you save $36. That 30% applies to selected sale styles only, and only while stock lasts, so confirm the product is in the sale before you checkout.
If you want the gemstone statement earrings. The deal Gemstone Statement Earrings For $22.49 is the simplest option: the earrings are offered at a fixed price of $22.49 on selected items. Use that deal when you are buying that pair, since the offer sets the item price directly and is limited to selected items while stock lasts.
If you want the Lauren skirt. The Lauren Skirt For $159 deal sets that skirt at $159 for the selected style. If you are set on that skirt, buy it at the $159 price; it is a selected style price while stock lasts.
If this is your first order and you will sign up to the newsletter. Sign up to the newsletter for 10% Off Your Order can apply to your whole cart once you have completed the signup. For a $159 skirt, 10% off would reduce the order to $143.10, saving $15.90, which is a lower total than paying the $159 price only if the skirt price is not further reduced by the sale. For a $120 sale dress, 10% off would leave you paying $108, which is worse than the 30% sale price of $84.
When to pick each offer, in short: use the 30% Off Sale Styles for items that are listed in the sale, use the fixed price deals ($22.49 earrings or the $159 Lauren skirt) when you are buying those specific selected items, and use the newsletter 10% off only when you are a new subscriber and no 30% sale price or a lower fixed price applies to the items you want.
Compare the applicable options for your exact cart and take whichever leaves the lower total. There is no terms statement here that says these offers combine, so treat them as separate choices and pick the single offer that gives the lowest final price for the items in your cart.
