Gift card bundle for trade

I'm getting back into couponing after a break. So I have no coupons to trade but I have cleared out my purse and have the following bundle:

Toys R Us gift card .71 left on it
Indigo/Chapters gift card $1.81 left on it
The Ultimate Dining Card (Swiss Chalet etc) gift card with $2.59 left on it
iTunes gift card with $15

I have no idea what is out in coupons because I'm starting out again. I'm looking for the best offer for the bundle.

Coupons for laundry detergent, pizza, cheese, pasta, juice, fresh vegetables and fruit and meats are always wanted. I don't need coupons for health or beauty products because I sell natural products. Also don't need coupons for ziploc or containers because I sell Tupperware.

Thank you for your time
