An awesome high-value coupon has just been released for $2.50 off any Alexia Item. This can be paired with the Target coupon for $1/2 at any store that will accept both. From what I've seen, the potatoes are usually between $3 and $4, so these coupons would make for a great deal even without a sale.
Also, coupons.com has a new coupon for 50¢ off one box of Zatarains Rice or Pasta mix. These are normally around $1.50, so this would be another good deal without a sale.
Even though using these coupons would make a great deal anytime, I will hold onto mine for a little while, hoping for a sale.
