Fantastic Bib, Way over priced on Amazon

The bib I would give 5 stars, the reason for the one star rating is the price. These bibs are excellent, as they seem to be the only ones that fit close into the neck and stop milk/food dribbling down the neck. BUT, on Amazon they are $14.99, at Toys R Us they are $6.99. I cannot understand how they can be so much more expenseive here.
