I emailed customer service about the issue and asking if the code could be applied manually on their end and this is what they responded with:Just a heads up ladies, I placed an order with Rue Gembon today and tried to use our coupon code and was told it was not a valid code. I tried a lot of variations before I gave up. Not sure if you guys have had that issue or not so I just wanted to give a heads up.
"Dear Breanne,
Thank you for your email and sorry for the inconvenience caused. There was a glitch in our system due to a clash with the cyber monday promotion. I will apply the 20% to your order and I just wanted to let you know it will only be applied to the three normal priced item, the code cannot be applied to sale items.
Please do not hesitate to contact me for further assistance."
So if any of you plan to use the code given to us in the box and for some reason it doesn't work, like it didn't with me, make sure to send customer service an email. I got a really quick response and they were more than eager to help me out and apply the discount.
