I've been getting bombarded with email offers for many months from shoes.com. Lots of spam mail. When I tried to use a sale offer, it wouldn't work. I tried 3 different ones and none of them worked. Even the ID ME offer didn't work. I noticed that the discount percentage would change as it went along as well.
Since I need new shoes, I didn't really care about a sale offer but since they offered one but didn't honor it, I'm not doing business with shoes.com now or in the future. Looks like they spend most of their time on marketing and not customer service.
