I just came across this on one of the blogs I read. I'm too embarrassed to disclose the name of this blog (Kirsten, shhhh). I've learned in this past year there are ridiculous amounts of gadgets, baby toys and accessories on the market. Living overseas and not being tempted to buy all this crap is a good thing.
Did someone really need to invent this? Is it really that hard to carefully push the cart up against the car before you unload it? Hmmm, as I type this, I realize... there are guys at the grocery stores here that unload for me, so I'm never in this predicament. But really, I don't think this is a big problem, unless you're unloading groceries in San Francisco and your grocery store is on a hill and the parking lot is on an incline. I would (maybe) justify their purchase, but come on.
Truly, I should just invent something like this, sell it for $19.99 and live happily ever after.
