Addition Elle are offering 25% off your entire order online today and tomorrow when you use coupon code 25TRENDS at checkout. They are still offering free shipping when you spend $100+ and you can buy from both Penningtons and Addition Elle together and use the discount, which is great as Penningtons are offering an additional 50% off sale prices today.
I checked with sale items from Penningtons and the code showed a discount at the full 25% at the bottom of the page, the prices shown in Penningtons sale pages are the regular sale prices, the further 50% will be taken off in the cart and those items are marked 50%
