What’s better than a deal? A discount on a deal. At certain Goodwill stores, there are extra bargains throughout the week. On Sunday, select items are $1.50. Students and military with ID get 20 percent off purchases on Tuesday. Seniors get 20 percent off on Wednesday. And on major holidays (like July 4th), most merchandise is 50 percent off. And if you go to www.EastersealsGoodwill.org and sign up for the email list, you’ll get coupons sent to you.
