I know...me too! All of a sudden nothing! I was getting them pretty regularly. Maybe I am returning too many things??
Don't know what their system is but it doesn't make sense because I have spent plenty there in the past few months!!
I used to get them all the time too. I noticed when I started to purchase more I stopped getting them. I opened a new email account and they sent me the coupons a few times and now they don't send them anymore. who knows
