I have to have mine, per my Podiatrist (if I choose to wear sandals, that is- and I LIVE for sandals!). We went to a local store when we were visiting Gatlinburg, TN over Memorial Day and ordered a pair through them (they didn't have the one I wanted in stock). After I had already paid, and got home, I checked out birkenstock.com and found that I could have saved about $5/pair by going direct on the website. I don't have any codes to offer you, just the suggestion of visiting directly to the birkenstock.com website. Good Luck!!
