Michaels Weekly Coupons and ads. Michaels also has “daily deals” that you can see on their website. For more coupons go to the link. The big coupon this week is the 25% off regular and sale items (read fine print) valid July 15th - July 21st, 2012. The sales on some things aren’t as good as last week but everything sort of evens itself out if you use the 25% off coupon (for example the tee shirts were 5/$10 last week and are $3/$9 this week).
