The top offer for MO&Co right now is the 10% off sitewide promo code at the top of this page, and it is best for nearly any full price fashion purchase because it applies across the whole fashion range. Keep the first order 10% off code in mind if you have not bought from MO&Co before, as that is restricted to new customers only. If you are shopping sale styles, check the sale reductions first because some sale items are marked down by as much as 50% and may save more than a percent code.
Small orders under $99: If you are buying a single item or a few pieces and the total will be under $99, use the 10% off sitewide promo code above; it applies to the whole fashion range so you get that discount on the class of item you buy. The Picks under $99 deal lists selected styles priced below $99 but does not add an extra discount, so the 10% promo code usually gives the bigger saving on those full price items.
First purchase: If this is your first order, compare the two 10% codes. The first order 10% off code is restricted to new customers only; if you qualify, it gives the same percentage saving as the sitewide 10% code but is limited to first purchase. Use the first order code if the checkout accepts it, otherwise use the sitewide 10% promo code above.
Buying sale styles: For items already in the sale, the sale price can be as much as 50% off. A 10% percent code applies to full price sitewide but may not stack with sale prices depending on item eligibility; if the sale price alone is lower than the price after a code would apply to the full price item, choose the sale. The sale is valid on selected styles only and needs no code.
Small extra discounts and selected item codes: The extra 5% off order code and the various 5% selected item or storewide codes are always a smaller percentage than the 10% promo code. Use those only if the 10% code is not accepted by checkout for a specific item.

When you choose, run the numbers at checkout and take whichever option leaves the lower total. No offer on the page states that codes combine, so assume only one promo code will apply unless the terms say otherwise.
