Ok so there are a few coupons out there you can receive from Playtex and use with the Target coupons that are out as well...
First coupon is the $2.00 Playtex Mfg Coupon found here
You must sign up for Playtex coupons and emails they will email you a coupon to your email within 24 hours
Second coupon is the $1.00 Playtex Mfg Coupon found here
You will find it on the home page bottom left
Third coupon is the Target store coupon found here
Look for the $2.00 Playtex Sippy Cup under Baby coupons
Target allows you to use one Target Store coupon and one Mfg coupon so you will be able to get a total of $3.00 off and $4.00 off one sippy cup. The Playtex Sippy cups range from $3.99-$7.49 so like I said you will be able to get some free cups or really cheap cups! Good luck and happy shopping :)
