Thanks for sharing Shannon.
For anyone interested in using it, it did not work when I tried to order the Trouser oxfords for $69.99. Once I added a pair of leggings on clearance for $14.99 it worked, which makes me think it probably only works if you spend over a certain amount.
I didn't end up placing the order because the price came out to be the same as the full price shoes and I don't need leggings.
