I think I voted wrong. I thought you wanted to know if we use other members codes instead of our own. I voted, "no but, I would". I use my own code but, I've thought about using others codes once in awhile just to help them out a bit.
It's funny, I just found out a couple months ago that I could even use a code other than gift cards. I've been a member since 2009! Think of all the $$ I could have saved, sigh. Now, I know to use one on all of my orders.
