Target mobile coupons

[t-rex]

I have finally moved into the 21st century. Just signed up for Target's mobile coupon alerts by signing up on their website. Target

They sent the following in my message with a bar code image included (I received this message via an iPhone):
$5.00 off Women's Denim Bottoms (excludes dENIZEN)
$2.00 off Enfamil infant powder formula 23.4 tub or 35 oz refill
$1.50 off Robitussin peak cold and cough relief item
$3.00 off with the purchase of 2 11/12in California Kitchen pizza
.50 cents off Target Cafe or Pizza Hut Exp. food or drink

All of these have a limit one disclaimer for each coupon.
