Pay a deposit to obtain a shopping cart. Get the deposit back when you return the cart. This sounds like a strange concept to some of you. But, the system is common throughout Europe. And it works quite well. Of particular interest to Americans, you see few, if any, shopping carts that have strayed far from their respective store parking lots. As a former grocery store employee (more than 25 years ago), I can attest to the straying nature of shopping carts. They just like to roam.
So, the system is quite simple. There are two slots for coins; one each for a 5 kronor or a 10 kronor coin. Depending on the exchange rate, that works out to something over $0.50 to less than $1.75 for your shopping excursion. So, in most cases, you really do want that coin back. Insert the coin into the slot and the chain connecting your cart to the one behind it is released. Reverse the process after shopping by reconnecting the chain to your cart. Voila! Coinage retrieved.
And, yes, TJ and I shop at Willy:s. We like Willy:s. Um, I mean we like to shop at Willy:s. Oh, you know what I mean.
