I love "dropping the price" on kids items.  At drop price you can shop and share about kid proportional items. Each time you share, the price drops, so collaborating with others to share drops the price faster. And when a low price is reached you are notified, but you can buy it anytime during the promotional period. Items have been lowered so much as less than $1. Here is one product i bought for $.94 from Drop price:  Tray Haven.

Tray haven is a great child proof barrier for feeding or playing children. You can easily place it around your baby's highchair, wheelchair, and stroller tray. It adjusts and buckles to fit snug to what you place it around. I got pink but here are some pictures from tray haven as well. Visit them on facebook twitter and on their website.
