Sydney's Closet currently highlights an Up to 73% Off sale on selected styles as the lead deal, and that is the best starting point if you are shopping sale items. The sale applies only to marked sale styles and is website only, so it suits you when you plan to buy items already reduced on the Sydney's Closet site. If you are looking at specific new price points rather than sale stock, the two marked product deals are the ones to use.
If you are buying marked sale styles, use the Up to 73% Off sale. The sale covers select plus size pieces across women and teen ranges and is the only offer that applies to sale inventory. For sale items that show a reduction, the sale price on the product page is the price you pay on the website; the up to 73% figure describes the largest possible reduction on eligible sale styles. This is the option that will give the biggest savings on items already on sale.
If you want the sapphire blue corset homecoming dress, buy it at the advertised price of $299. That product is listed as a specific deal with price as marked and is available while stock lasts. Because it is a named deal, you pay the shown $299 on the site; the sale offer only helps if that exact style is also marked as a sale style on the product page.
If you want a short white dress in plus size, choose the From $159 deal. That listing sets starting prices from $159 for eligible styles and is valid while the offer styles remain. The price as marked on the product page is the one that applies for your chosen size and style.
If you are comparing a sale item with a marked product deal, check the product page prices. The sale offer applies only to items marked in the sale; the $299 and From $159 deals apply to the specific listed styles at their marked prices. If a dress you want appears in the sale at a lower price than the marked deal, choose the sale price. If the product page shows $299 or $159 for the item you want and it is not a sale style, use that deal.
To choose between the options, take whichever listed price or sale price leaves you with the lower total at checkout. No newsletter or promo code is required for these offers, and there are no stated stacking rules in the listed terms, so use the single price shown on the site for your item.
