Last week I got a TRU mailing. Inside was a card that gave me $15 off a $150 purchase. It was basically a promo for their 'big toy book' that is good through November. My neighbor's coupon was $25 off a $250 purchase so I gather there are different denominations out there.
One of the deals in the book is that with a $100 purchase you can get a free Lion King stuffed animal (Simba or Nala).
The stuffed animal is very nice. Without the $100 purchase it rings up at $29.99. Turns out that $29.99 COUNTS towards the $150 on my coupon. So today I bought $120 worth of stuff at TRU and a $30 stuffed Simba (total $150). They took $15 off and then subtracted the $30 for Simba. This made the discount slightly better than 10% and I paid $105 for the $120 worth of stuff plus a free Simba (before manufacturer coupons).
You guys can use this loophole too if you don't want to buy quite as much stuff as your coupon encourages you to! HTH!
