The only reason I ever thought of buying a shopping cart cover was to pad the skinny little wires, which, from my vantage point as an adult, look mighty uncomfortable for small tushes. But then I'm always shoving my coat, or their coats, hats and all manner of pillowy belongings in right beside them anyway.
But physicial comfort is not what the makers of these cute little liners are selling us; they're selling us supposed protection from the big, bad germ bugs looming on the handlebar; leftover, no doubt, from the unwashed, diaper diving hands of some other mother's little heathen.
That's what they're selling.
Of course, according to Healthytoys.org, with this particular cover -- The Shop 'n Learn Cart Cover made by Fisher Price -- you also get 153 parts per million of lead, 240 parts per million of bromide and 19 parts per million of Arsenic.
Kinda glad I opted for the common cold.
