I received one of the emails and it included the 60 percent off one regular priced item.
It worked out great for me because I needed to purchase some canvas to recover part of my sofa base. Normally $9.99 a yard (60 inch wide woohoo!) and not on sale so I ended up getting 3 yards for around $12.00 (=).
They make you work to find something not sale of course, but there are some regular priced items in the store.
My mailer advertises keepsake calicos on sale (I believe 50 percent off) at the end of month, and then there is a 20 percent off total purchase good for a few days at the same time.
